I think the concept of this one is good, and I like the way the art looks, (Although, I think I would cut down the chromatic aberration just a tad, it's a little aggressive ) but there's definitely some balancing issues the game didn't really get hard for me until wave 9 on my first run, and the previous 8 waves were extremely easy, which wasn't super fun. Then unfortunately, when I died on wave 10, I was walking down as I was hit so when I was instantly moved to the upgrade room and then accidentally walked out without buying anything because I had no time to react.
I also think some feedback for hitting enemies and being hit yourself is really needed. Right now, hitting enemies feels very weak, and I had a couple waves where I looked up and saw I had one or two hearts left when I didn't remember being hit at all.
Overall, I think this is a really cool concept, and with a bit of polish it'd be a really great game.
