A downloadable game for Windows and macOS

by CHUMBOSOFT ( rmntwitter / tumblr )


Play as Eve Staccato and roam through a world full of Mogwai, magical creatures from another world. As a Conjurer, you will fight alongside Mogwai in battle to help those in need–and heal the rift between two worlds. 

The Den–the Mogwai world–has been cut off from the Outset for nearly a century. However, its intrigue and turmoil ripples through both worlds, turning a simple errand from your country clerk grandfather to a grand adventure. 

Meet friends, make enemies, and explore the world using your Mog friends' magic powers to make your way. Run past or fight feral Mogwai as they lurk through the environment. Fish, collect cards, solve puzzles, weave through an onslaught of angry chickens–and forge lasting friendships that continue after the main story. 


  • A lighthearted, feel-good game with a character-driven story.
  • Help and befriend a varied and charismatic cast of Mogs and humans.
  • Your Mog friends can do more than fight--navigate and solve puzzles with their powers!
  • There's tons to do on the side, from fishing to filling out your in-game card collection.
  • Over one hundred original enemies to encounter!
  • Over 13 hours of gameplay with multiple endings and a post-game!

i cant get the gate open somehow :s

Do debuffs and the like stack? And if they do does it show when you reach the limit?

Pretty good demo, I have one question though, how do I fish? When I select Eve and press W in front of a mass of water, she throws the fishing rod, then I wait until the dots disappear and then the question mark appears. At that point, every single time I tried, the catch goes away, how am I supposed to reel them in? Other than that I really enjoyed it.

When the "!" shows press Z then follow what it says next. Enjoy the fishing life =D

Oh yeah, you're supposed to hit the Z key when the exclamation mark shows up. I guess it's a little confusing going from W to Z with no real explanation, so I'll be sure to change it to reel in with any button for future updates.

Thanks for the help, I appreciate it :)

Damn dude, that was good. Almost forgot I was playing a demo at times.

Also, can't help but notice that grumblr.com doesn't exist yet.

Aw, thanks! Yeah, it's lengthier than most demos, so I can understand that feeling lol. Glad you liked it!

Grumblr is either a blogging site or a hookup site for monsters. It is a mystery!

Hello, I came from NitroRad's video. I just finished the demo, and that was one of the most charming experiences of my life, and I can't wait for the full version. My only "complaints" are what he mentioned in his video, but I agree that none of those are deal breakers at all. But I have a question, will we be able to transfer our save data from the demo to the full version? If so, how would that work?

NitroRad's videos are great! I really love his constructive criticisms in his reviews. Some people on the team are big fans, myself including. We were really grateful to have the game reviewed by him. We weren't expecting it but it was such a nice surprise.

It's so nice to hear that you liked the game! And yes, the save data can be transferred. We'll put out an explanation on how to do it when the game comes out but, basically, all you have to do is either overwrite the files from the full game onto the demo, or (easier way in my opinion) is transfer the "save" folder from the demo to the full game. We've tested it and it works just fine! So no worries there.

Oh, that's really nice to hear. I'm terrible with messing around with files and stuff by myself. So instead of overwriting the files, there will be an option in the full game that will ask if you want to transfer your save file?

Sorry if I'm misinterpreting what you're saying.

It might be too hard to write a proper save transfering program, but transferring from your current folder shouldn't be too hard. When the time comes, we'll make some gifs showing off the process to make it even easier.

Oh, alright. And you'll have the instructions written down somewhere too, right?

Really? Time to grind every single day up until release then. /s

Oh! Transferring is a possibility? I wasn't gonna play before release, but in that case...!

When might this get released? I'm really looking forward to the full game!

Our aim is the end of August, but if we end up delaying it, it won't be for no more than a week or so. Right now, we're just polishing and fixing whatever we can in this time span. We're really hoping you'll enjoy the game when it comes out!

That is great to hear! I found out about the game through NitroRad's video. I loved everything I saw, aside from agreeing about his point that attack animations clash with the other graphics. But I can only guess that was because it was a demo. I'm eager to see how it looks and plays after all the polish and completion is done!

Yeah, I know several people, including myself, on the CHUMBOSOFT team are quite fond of NitroRad's reviews! We addressed the issues with the battle animations in our latest blog post. It's a valid critique, but we might not be able to implement new battle animation graphics in time for the release. The least we could do is make it match the game's resolution. And, thank you! I hope you'll have a great time playing the game when it comes out!

Ah! I just read the post. That's fair, animations like those can be quite tricky to draw! It's not a make-or-break issue for me, but I agree that at least scaling the effects resolution to match the game would make it mesh a lot better. If you do end up making unique ones later on down the road with a patch that'd be awesome! Considering the rest of the game's aesthetics, I'd love to see what could be pulled off. (Perhaps an artistic fan could even contribute to the effort if it's still proving difficult even then? I'm certain this game will earn some talented fans, if it hasn't already.)


(Maaan, if a fan did that, it'd be really cool ;;...)

So yeah, for now we're going with resizing the effects to make it to the release date. I'm probably going to end up indexing them to at least keep them from being too blurry (since they will be a smaller resolution now). I really do want to make a patch for it in the future though since it's the biggest complaint for the game right now.

Hello i only made an account so i can say:GREAT WORK! This game looks,sounds and feels amazing i have never donated to a game but i would do it for this one cause it looks so full of potential,keep up the good work i'm eager to see how this goes :3

Aww, how nice! Thank you for the compliments! As for donations, we won't be taking any right now since the game is planned on being priced at $5 with a "pay what you want" option. So if you ever want to donate, you'll be able to do so that way!

Also itch.io is a great site. I hope you have a great time here!

Hey i really dig your project any way to send you a donation ?  it won't be much but im sure anything helps

That's really nice of you! The thing is, we're planning on having the game be priced at $5 with a "pay what you want" option. You can donate that way when the game comes out <:



I'm in love  and  waiting to buy the full game  ^_^

Thank you! 

We'll keep working hard so we can release it on time!


Lovely game, will definitively buy the full release when it's finished.

Heck, would even give my money now just from the quality of the demo.

I think we're fine on keeping things free at the moment!

But thank you for the kind sentiments, that's super nice of you.

Not even considering opening it up for donations/tips, or would that give obligations you'd then have to follow?

It might make things a bit more complicated, but I'll ask the rest of the team so we can figure out a way to handle it.
