Mechanically simple but deeply enjoyable. This is a perfect mobile type game.

What a pleasant surprise. I found your use of the theme to be absolutely spot on! You've used it in an original way that incorporates a fun mechanic which is easy to understand and fun to play.

I must add, at the beginning you see nothing but a level, not knowing what the mechanic, and controls are you are forced to figure it out yourself, also you only get to see the intro AFTER you've succceeded at that, I loved it! Very cool.

I'm totally waiting for the post-jam version, this is a really great puzzle game!
I love the simplicity of your pixel art, and the mood created my that little touch of color with a gray/light-blue shade.
The story behind this game seems solid, and even without too much complex twists or big storylines it would still be an interesting journey.
Even though gameplay and controls are too simplistic for a PC/Mac version, with some soothing ambient sounds effects and more levels I think this could be a great puzzle game for iOs/android devices. I'd definitely install this on my tablet.
What could bring this to the next level and make it attractive for PC/Mac players too is, in my opinion, a level-editor component or a speed-run singleplayer/multiplayer mechanic aside from the main story.

I just get a black screen on windows. (installed using itch.io desktop client)

Playing this on a phone is a must, it really enhances the experience. I love all the little animations and enemy movement, and the graphics are simple but cute. You should really polish this and publish it on Google Play.
