This is such a wonderful, beautiful game. Thank you all so much for your hard work.

Do you guys have a plan for porting the game to Nintendo Switch??? You know the game would fit perfectly!!

(1 edit) (+1)

Just wanted to say thank you!

What a charming and fun game you've made, I'm having such a great time playing it right now. It hadn't been a great New Years Eve for me, but this game brightened my day   : ) 

Beautiful game, are there any plans for making a mobile version of this? 

I love this game. Thank you so much for making it. I want to write a longer review at some point as a better "thank you" to the devs, but the characters are great, the music is fantastic, the battle system is engaging and challenging the entire game, the art and graphics are outstanding, and everything is charming in a way so unique to Heartbeat itself.  It's just a fun, fun experience that brought to mind all the GameBoy Advance games I used to play when it was around.

I find the game to be very well-executed overall. There's a few places where I would have liked to have seen more--maybe more or better-developed puzzles, or perhaps more sequences where the battle system itself is changed up, or maybe ways to make fish and EXP grinds a little more interesting--but overall the game benefits from its relative simplicity.  I really enjoy the writing and the story, but I always felt like I wanted more of it. There's the makings of a great tale about wronging and seeking forgiveness, and being wronged and forgiving, but it's slow to develop and underdeveloped by the conclusion.

None of that takes away from just how much fun it is to be playing the game. I would encounter new enemies and send screenshots of their designs to my boyfriend as I played, I'd hope to hear certain music tracks again, I'd hope to get more dialogue from my favorite characters (namely, all of them). It's a beautiful experience full of warm colors, lively characters, and great personality.  It's also perfected the lost, difficult art of the boss rush, and you get to feed the cutest little baby moth ever. So,  I hope I get to have more experiences playing games like those I had playing Heartbeat.

Hi, gasst, sorry for the late (and short) reply. I don't really quite know what to say because I'm bad with words but your message made everyone at Chumbosoft very happy ; - ; Thank you so much for taking the time to leave us such a lovely comment ♥ Stuff like this keeps us going and doing our best for future projects. Thank you!!

Hey there just droppin by to say one simple thing: This game is totally more than I had hoped for. I'll be honest, for a game on itch.io I was expecting, maybe, an OK-ish story with some basic tropes and a half-assed fighting system.

Now, I just got to Otecho but already this game has blown my expectations out of the water! Did you guys make some deal with the devil? you know... Midnight at the crossroad? Otherwise, how do you explain being this good?

Anyhow, Merry (belated) Christmas and Keep up the great work!


It means a lot to hear that, sneakyfletcher ^q^ <3 HEARTBEAT is just the product of lots of love, care, and the things we like, what we liked from RPGs from our childhood, and stuff like that!

We hope you had a lovely Christmas yourself :]

Please translate the game to Potuguese !

Dropping in to wish you guys an early Merry Christmas! 

Thank you Thaco!! We hope you had a lovely Christmas!

Hello. I'm currently at the second area in Peppy Jack's Cave (the one with the closed off gate in the center, one invisible path that leads to a dead end to the left and a hookable platform to the right) and I see no way of advancing. Could I get some help? Thank you.

Hi SpookSpark! Try using your blue ghosty friend!

That did the trick, thank you. Wonderful game by the way, loved it from start to finish. I hope the project was a success, and I wish the team all the luck in future projects.

Sorry for the extremely late reply! We're very happy you liked the game; I'm personally very proud and happy  to see the game getting so many compliments from nice people ; _ ; Thank you so much!!

I've completed the fishing request  and they ask me to beat some penguins with Tate. But everytime when I encounter those Pengy,  I always got a straight K.O. no matter how I do. 

Can you help me please? I need some tips

Hello Kirara! You have to go through the ship and find three items: The Boombox, the Soup, and the Gun Repellent. When you encounter Pengy Crunch'n without the items, you have to use Tate's skill "Tate Escape"; when you do have all those items, you have to use them in order to defeat Pengy Crunch'n.

(1 edit)

Thank you very much! I'll figure it out how to use those items later. By the way, Can I ask again? Jake already in his human form but he hasn't give me his core, is there something I missed?

No problem! Let me know if you have any more inquiries, and no, Jake won't give you his core u_u 

Hi there, I just bought the full game (after playing the updated demo!) and I've successfully moved the demo save folder items to the full game. Though I didn't find the save folder under app.nw in the full game contents, I copy and pasted the whole demo save folder there and upon running the full game it loaded my save file. But when I try to save in the full game, it doesn't let me (it gives me the "you can't do this action" sound). Is there any way I can fix this? Thanks!

Hi gupjo! Sometimes Mac has troubles reading/writing the folder, just try unzipping the game folder somewhere where your mac can read it well, like the Desktop! It should work then :]

(1 edit)

Hi Sil, thanks for the reply! I tried unzipping the game in my Desktop, but I sadly still can't save :( 
EDIT: I downloaded the game on my Windows partition and I can save normally! I'd still like to try to get it to work on Mac though (to transfer my save files), so any suggestions would be great :)

That's very odd :[ Mac's quite finicky and to be honest, none of us has a mac so troubleshooting is kind of hard to do u_u also i hope you downloaded the Windows version in the Windows partition! There was a user who played the Windows version on their mac through the index.html file and lost their saves because they were stored in the browser's cache @_@ 

Hi! I'm sorry, I don't know if it's just me or what, but I haven't been able to find Ingress Path. Can anyone point me to the place?


Hi! Sorry for the late reply, Ingress Path is that area that's initially guarded by a snowverian hunter when you first go through Arctario Cave.

I recently bought an Acer One 10 because I needed a bare bones laptop that was just small enough for me to bring pretty much everywhere. Obviously, I had to try and install HEARTBEAT on it, I'm glad  it runs quite well and with headphones I don't have to compromise hearing the terrific soundtrack on the builtin speakers.

Welp, there goes my productivity...


Ahaha I can relate to that very well :] We hope you have fun!

Signed up for this site literally to ask if there are any plans to bring this beautiful looking game to the Switch? I bet they would love to have you!

Hi, Leviathanos! As much as we'd like to, at the time is not possible u _ u) thanks for the lovely compliments!

Congrats on the Steam release! It's awesome that you gave us keys for that version as well. I just recommended it to some friends. Good luck, and much success in the future!

Thank you, Dt3r! For the support and spreading the game with your friends :]

Hey I was wondering where I find the steam keys if I had HEARTBEAT already.

Hi! You can find the steam key if you go to your purchase page on itch.io (it has to be through the web, not through the app), and if you go at the bottom (past the Download buttons), you'll find an option that reads "Generate Steam Key".

Thank you Lady Lily for the congrats! ^<^) And also thank you for letting us know

we'll edit/delete your comment though because we think it's counter productive to link the site here u _ u We appreciate you telling us though!!


oh sorry for that ^_^'

I wanted to tell you in more discreet way but i couldn't find your e-mail.

No problem, Lady Lily!! We're always available at our Twitter too ^<^)

Congratulations on the Steam release! Hopefully more people will catch wind of this absolute gem of an RPG. I came across it by chance, and was so impressed by the original demo that I simply had to make an itch.io account to buy it and support you! 

Thank you so much NineTailedFox! We really appreciate the support ^<^) We hope you have fun playing the game!!

Hmm, I got notification of an update, are there patch notes pending?

We'll be working on Steam changelogs soon; for now they're all miscellaneous bug fixes.

Here as well, right? I don't use steam.

Oops my bad! Last update we did was v1.1, which is the newest version that came along Steam; but yeah the patch notes are pending for now!

Congrats on the Steam release! 

Thank you ThacoBell!!


Thanks for Linux  ^^

Thank You for the support! :D

Greetings! I really enjoyed Heartbeat, its one of my favorites.

I see that the game was launched on Steam recently. Is it possible for someone who bought it previously to get a Steam key, or is it only for people who buy it from now on?

Hello! We're very happy to hear that! :]

If you purchased the game here, go to your itch library, check the download page, and at the bottom there should be a "Generate Steam Key" button.

Is there a secondary method? I have been looking all over the page and cannot find the "Generate Steam Key" option. When I originally purchased the game I had an issue with the itch app not letting me download and had to download it through the itch website, so maybe that's why?

yo, check in the thread for my fix for this (use your browser, not the itch app), I replied wrong :p

(1 edit)

Heya, I was having the same problem; it looks like the "Claim Steam Key" button is only visible on the itch.io web page (I'm using Chrome), NOT on the itch.io app. If you follow the directions after going to itch.io on your browser, it works perfectly.

EDIT: er, oops, this was meant to be a reply to Deeva!


Thank you!!!

I just played through what feels like the majority of the demo (had an unexpected crash) but omg I am quite dazzled at how quickly I lost track of time! I must know; how many people worked on that for how long using what engine?! It is quite mesmerizing :D!

Hello, Xarcolt! Yes, the demo still has crash issues, but we will be uploading a new version sometime without the crashes :]

We're very happy you enjoyed the demo! We're 3 people at CHUMBOSOFT, and we used RPG Maker MV. Thanks for the kind words ^<^

Incredible! Neat use of the engine. Trying to make a decent RPG myself but in a far-abandoned engine (DarkBasic Pro). Literally it's just planning a wall of code. No UI other than anything you program yourself. *reinventing the wheel* It gets rather discouraging but a vibrant game like the one you three made is quite uplifting! Keep up the good work.

Hello; I just downloaded the demo onto my Mac to give it a try and I was really excited by just how cute everything was! However, I found that I cannot create a save file. I can go into the save system , move over any of the save file options, but it will not let me save (select). The auto save does not seem to be an option either, as it is not available to load from in the loading screen. Any ideas as to why this might be happening? I can only guess that my computer is not allowing the game to create saves for some reason, or that the game cannot create them on my computer due to something I am not aware of. I am new to Itch.io, so there is a chance that there is something I need to do that I haven't. Thank you in advance for your help~!

Hello! Sometimes Mac has troubles reading/writing the folder, just try putting the game folder somewhere where your mac can read it well, like the Desktop! It should work then :]


Thank you for the help! It work just like you said; what a silly thing for Mac's to be picky about!!

(1 edit)

About 7 days until the release of the steam version! Woohoo! One tiny question, if we've already bought the game here, will we have to pay for the game again for the OST? Or will you distribute steam keys for those already paid for the game here for access to it? You've probably already answered this somewhere buried in the comment section but Im just curious and so excited for this game to come around full circle! 

Hi! Those who already bought the game on itch.io can get the soundtrack from harmonicblend's bandcamp, or as a DLC from Steam, for 7USD (in both places they are the same price).

Fresh players will be able to buy the game and the OST as a bundle for 20USD on Steam :]

Dont worry about asking questions that have already been answered! Let me know if you have any other inquiries!


Thanks for the quick response! I'll buy it as soon as possible! ^^

Will this ever be on steam?


On December 12th, yeah.


I checked this place on the daily just for this post. Thank you good sir.

Does this patch fix compatibility with the itch app? If not, how do I update the game when standalone?

Hi! No, Patchv1.09a contains a hotfix to some bugs in the post-game dungeon and other miscellanous fixes. We still haven't looked into the compatiblity with the itch app.

In order to update the game when standalone, all you have to do is download the Latest Patch, and copy paste its contents into the game's folder.

Thanks! Good to hear I don't have to completely re-download the whole game again.

That is one of the issues we have on the itch app actually; we're gotta figure out how updates work so it doesn't make users re-download the whole game everytime there's a new update, and even then, it was giving users weird errors/freezing. Plus, manual updating is way faster :]


hey! heartbeat has been a great game so far, the designs are cute, and I feel interested in the characters! im not very far yet tho
i have a problem, however
i ended up messing up in this optional puzzle, only getting 2 out of the 4 chests, and due to my completionist attitude, or perhaps ocd more likely, i can't get over missing only two of these chests
i leave the room and the room stays the way it was before, is it supposed to do that? is there supposed to be one of those reset buttons nearby?


Hi! We're happy you're enjoying the game so far!

This is the only puzzle in the game that has no reset button - once you start it, theres no going back. They're not important items anyway, the chests that you're missing only had a Familiar Perfume (+50 Beat recovery item), and a Sugar Bun (+50 Pulse recovery item) in them.

I'm having trouble with the gate puzzle in Froxeter Forest. I understand I can charge the switches and charge again without pressing the confirm button- However I'm having some trouble with the timing and I don't think I'm doing it right. Could I get some in-depth help please?


Hi! I apologize for the late reply; I'd advise that, as soon as you crash with with first switch, you mash the skill button , and change directions while she's revving up. As long as you activate the skill right after you crash with the switch (hence why mashing the skill button is recommended), there should be enough time to do it.

If you still have trouble, don't hesitate to contact me on the Discord server, or PM me on Discord directly if that is more comfortable to you (Sil#0579)

Thanks so much! I thankfully got it. My timing was off super bad for a while there but, I appreciate the help!


No problem! Let me know if you have any other inquiry, I'd be more than happy to help.

Not gonna lie, that puzzle got me too- but the challenge was fun and I ended up getting through. :D Great work on getting that timing down. 

Glad you were able to get through the puzzle and you found it fun :D Let us know if you have any inquiries!

(1 edit)

Oh dear, I think I broke it. There's that puzzle in the spoilery postgame area where you have to hold down the plants using rocks, because they regrow too fast to cut them all in one go... except turns out one of the plants doesn't give a damn. Even better, thanks to the placement of that other plant on the left I can't pull the rock back out of there either.

I've seen a few bugs here and there, nothing too bad, but that one makes things straight up unwinnable without reloading a save. You probably should get that fixed.

Hello! We're aware of this issue and its fix will be available on the next patch; however, if you'd like, you can send me your save on our Discord Server, or send it through PM to me (Sil#0579), and I will fix that for you manually.

I am stuck on the puzzle in Cirruwa Forest where you have to use Lo's slash ability on the plants to open the gate. =( Does anyone have any advice? I'm not sure what order I should be doing it in.

Hi Jessi! In order to open the gates you have to burn all 4 plants in no particular order (there's one on the left top that's easy to miss) before they respawn.

Thanks,Sil. :) Puzzles are not my strong suit lol.

No problem Jessica ^q^!

How do you complete the gate puzzle in Froxeter Forest?

Hello Jessica! You have to crash against them with Chip's ability: when Chip hits a lever or a wall switch in the puzzles, it activates automatically. Thus, instead of pressing the confirm button, all you need to do is press (probably mash for maximum success) Chip's skill button, and immediately the direction arrow you wish to go before time runs out and the gates shut you out. You also don't need to move away from the spot you landed– immediately press the skill button and change directions while she's revving up to continue.

I did it! :D Thanks so much! :)   <3 <3

I bought the game some days ago and before I go right back I wanted to know how having played the demo affected the full release or how am I supposed to let it know that I played the demo. If there is a FAQ section where this is disclosed then please point me to it.

Great game, I'm glad it got a full version because the art style is just... Damn! 


Hello, sneakyfletcher! There's a readme file that comes with the game  with instructions on how you can transfer save files from the new demo to the full game. I'll copy paste them here for conveniency:

1. Go to to HEARTBEAT root folder and find the save folder. If you've downloaded on Windows, it should be like this:
[DEMO] > www > save

If downloaded on Mac, it should be like this:

[DEMO] > Game.app > Contents > Resources > app.nw > save

2. Grab the files from this folder and copy it into the same location for the new demo.

For windows: [FULL] > www > save

For mac: [FULL]> Game.app > Contents > Resources > app.nw > save

3. Once your save files are in the save folder, open the game normally and you'll be able to continue from where you left off on the demo.

We hope you enjoy the full game!!

Thanks a bunch dude! I guess my lifelong habit of glossing over read me's has yet to pay off...

I´ll keep on playing the demo and getting the Tickets before I move on to the fully fledged goodness 


No problem! Let me know if you have any more inquiries!

Just got my little moth buddy.This game is so cute! :3

I'm glad you're enjoying the game, Jessica! :D

Thanks,I love it! <3 

Hey, I noticed this isn't compatible with with the Itch app currently. Are there plans to make is so? Also, whoever is your artist, kudos. I haven't had a chance to play yet, but I bought the game base don the strength of its art alone.


Hi! Yes, the game was harder and confusing to update through the itch app, and updating it caused it to take a while opening and such. We'll look into it once in the future, as we're not completely sure how the itch app works for the moment. Sorry for the inconveniences!

And we're glad you like the artist! The lead dev Shepple was in charge of the art direction and most of the graphics, I helped with CGs and some graphics here and there. Thank you for the lovely compliment, and we hope you have fun!

I'm looking forward to having the time to play it!

Hi! I've emailed you to the email in your username (due to security reasons), regarding this issue. Please check your email inbox!

Hello, I have pretty much 100%'d the game, or so I think, there's this hook and lever in the cirruwa entrance I still have no idea what to do with, is it supposed to be inaccessible?

Hi, you have to access the lever by jumping over the fence with Rex, which is currently not possible due to a tiny bug, and then use the Hook Skill to get a secret weapon for the Hook Skill character.  The fence will be fixed in the next patch, we apologize for the inconvenience.

Hey can someone help me I'm on mac and can't save it 

Hi! It's because sometimes mac has troubles reading/writing the folder, just try putting the game folder somewhere where your mac can read it well, like the Desktop!

So I checked twitter again, but I can't find any link to the soundtrack from harmonicblend. Their website doesn't seem to be working properly, either. is anything happening on your front or is that entirely on them?

Same here! I love this game's OST and can't wait to listen to all my favorite tracks, I hope a link is provided soon! >u<


We're very happy you're excited about the OST!! We will make an announcement when the OST comes out, hopefully soon :]

Hello! We haven't released the OST yet, it'll come out when the game is released on Steam. We will be making an announcement when that happens though!

Regarding the harmonicblend website, the issue is on their end. The OST will be available at their bandcamp, or as a bundle with the game on Steam
