What an interesting mechanic, it seemed very innovative. I don't recall seeing anything like it anywhere else.
I found it quite challenging; in fact, I got stuck on some levels. I missed having a restart button; I ended up closing and reopening the game multiple times. I didn't manage to complete all the levels.
The art style is good, and the sounds were an interesting choice, but I would have appreciated some music.
I hope you continue developing; you have potential.
