Great concept!

The main mechanics is really creative, and well implemented. I didn't encounter bugs in my playthrough. I do like the fact that you have levels that slowly introduced more mechanics for the player throughout the game. However, I did find the puzzles a bit too easy overall.
The music is fun, but I would have liked to see sound effects for sure. The visuals are ok, but personally I don't like the mismatched pixel density.
Overall a fun entry to play. Good job!
