A very interesting and charming concept for a game. The pixel arts are really cool, i love them. I would love to take a peek behind the physics of this game, I feel like I'm going to get a Bachelor in Physic if I do.
However, I want to point out a mayor problem with the game.
1/ The Solution : For a few stage, The solution for a puzzle game must make a player feel they are smart for figuring it out. However, some puzzle here require pixel perfect placement to solve, or it feels like so. Which is a mayor problem for the game.
I think with a better difficulty spanning and a better tutorial overall. And with a lot of polish, the game can be really fun and unique to play around with.
Overall, a pretty interesting concept with a lot of potential. 7.5/10
