Pretty fun short game. I liked solving these short puzzles a lot. The visuals are simple, but quite cute. The black rat sprite at later levels move back and forth repeatedly when you run into him though, so maybe you could look into that.
The mechanics are very intuitive and controls are easy to learn. One thing I didn’t quite like however is that the different objects move at different speeds compared to the player, which felt kinda weird, although I understand that was maybe necessary for the puzzle designs. This game reminded me of the game Braid by Johnathan Blow.
The sounds and music are nicely done. Overall a pretty good entry, good job!
