Hi! I gave your game a shot, impressive for a first game. The aethestic is pretty unique from what I've played before..
If I could have one change made it would be more feedback when you hit an enemy, whether by hit marker on screen or some clear audio signal. There was also a bit of delay between hitting an enemy enough and them falling down, made it a bit confusing but generally there were so many enemies I guess it didn't matter too much!
What changes do you have in mind for the future? Different enemy types?
All the best with your game.
