I rated this during the jam, but didn't manage to comment. Fun game, I like the unique idea of a character looping on the vertical axis and the roguelike elements of only being able to select specific upgrades. I managed to beat every level easily, as I picked up a fast shooting weapon in the beginning and added damage and pierce upgrades to one-shot most enemies. The enemies designs are enjoyable to look at, even when the game is getting chaotic with loads of bullets.
