This game was actually pretty fun and relaxing!
The art was simple, but clean and very appropriate for a mobile game. The sounds also complimented the art style perfectly, with both being kinda cartoony.
My only real critique is the fact that the music sounds kinda solemn and mournful. I know the music wasn't made by you and it wasn't actually too unfitting, but it still just felt slightly out of place.
Other than that, fun gameplay loop, clean art style, nice job!
