I like the implementation of the theme. The game is very creative and the gameplay is unique.
Aside from the game, I have some visual remarks on the character. I realized that the characters move animation plays until it finishes before switching to idle. This makes the game feel visually less responsive. Also, the largest part of the character which is his head does not change a lot when moving. This makes it harder to tell visually when he is moving. I believe improving at these areas would make for a much better character animation.
All in all, impressive game with a fresh idea.
