It crashed here for me first time I did the purple pentagon, I was about halfway through, the music carried on playing so possibly a different bug to the one you mentioned 😭 Otherwise though, pretty much perfect entry. Nailed the theme, explored the concept well and didn't ever feel stale. Music was a bop, and dynamic too!!! Visually excellent, nailed the spirit of the "limited shapes" restriction. My only real complaint is that I want more (and it is too easy, probably a good spot difficulty-wise for a game jam but I did the entire thing without being hit lmao). Just excellent, well done.
