A lovely game, very classical for a jam. The core mechanic and its developments are interesting (though I ended up being stuck on the two enemies, a brown button, and a tilted jump pad level). The implementation of sound but not visuals makes it feel strangely timeless stylistically - too clean for Atari, too simple for anything modern.
The movement is pleasant, the puzzles are fun. One and only one problem I could find was the lack of a reset button. Manually ending the loop would have made it feel much smoother and faster-paced.
A great submission!
