I like that your main tool for killing stuff is not under your direct control. It makes it so you have to learn how the game works to be able to do something useful. Spotting that enemies lump together if you stand in the middle of a group and using that to get a big combo was satisfying.
I do think 2 minutes is too long to survive. I like more action filled games, and this stays quite slow throughout. I’d rather have to survive maybe 40 second but with the game being harder.
Also great use of the theme! It makes sense, and I think it’s a fun interpretation. Good work!
