Nice game! My favorite is the triangle :D
I'm sooo bad with the circle though. Once I start getting in a groove I can get decently far but sometimes my aim is just terrible lol. I really enjoy the premise, and your music and general aesthetic really contributes a lot to the game. Had a lot of fun with it, kind of interested in what you imagine the other shapes can do!! I imagine hexagons would be pretty sick. Great work!
