Pretty cool game idea! I'm curious if you were inspired by the game Titan Souls, I do really like the idea of ricocheting the bullet as the main mechanic, while it can have a lot of depth, I do think it's a bit too hard at the moment, would be nice to have a way to slow down time in order to think about your shots more carefully, I kinda gave up on trying to do fancy things when I just got surrounded by enemies after wave 1. Still pretty cool though, great work!
