Really cool idea, loved the art! I'm not sure if the game is supposed to be "on rails" (something like guitar hero), but if it is it would be nice to have clear lanes to see which lane you're in and which lane the items are coming. Either that or more free movement to make if feel less like there are only a few lanes you can be in and for a bit more control. Also not sure if there is a real reason to try and catch the good stuff (other than cosmetic) as you're already on max purity at the start so I just sat on the side and none of the bad items seemed to hit me. Cool game though, congrats on your first game jam. Good job!
