This is great. Cute, fun puzzles with a clever design. Quite possibly the best puzzle entry I've played this jam.
When I ran it the first time there was something wrong with the controls. I could move with the arrow keys but AWSD did nothing. The arrow keys behaved differently too, they respected key repeats so I would continue moving if I held the key down. I almost gave up and assumed the game was just hopelessly broken until I read the comments and it was clear that it worked for other people. Reloading the tab fixed the issues and the controls worked as expected for the rest of my playthrough. I'm running it in Firefox.
