Really neat idea.
Overrall, the game felt a bit slow (maybe because I was playing in the browser). The lack of music and sfx was really sad (but understandable for a jam game).
The art, while simple, is well made and the levels are interesting. It's a shame theres only one level where you have to "shatter" the pieces, but it's probable because of the time constraint.
Other than that, I think the game would benefit from a "undo" button.
Good job!

Thank you! Sorry about the performance issues, I was coding this extremely recklessly.
There's definitely further interesting stuff I could do with the level design. I was a bit worried that the puzzles could quickly get extremely difficult for a jam game if I wasn't careful, especially with a lack of an undo button and the shoddy framerate.
One of these days I'll make a game with sound :)
