I think this is a really well designed game with one fatal flaw. There is a lack of enemy variety or challenge that makes the loops pretty same-y after a bit. The upgrades are great and make it so each loop feels a bit unique. But the way you receive them randomly makes it so one loop could be really fun, but then the next 3 loops could be not fun at all. The good loops you do have though are like, really fun. Overall a solid game.
