This is a very fun idea especially if taken further and made faster/with even more enemy variety, some criticisms:
- The background music beat was really repetitive and annoying to me unfortunately, the music effects from the enemies appearing were fine
- It felt unfair to get hit by the shapes appearing from outside the screen, as there is no warning. Should either have a warning something is coming from there, or they shouldn't be able to hit you before they properly activate
- When I played, my characters position somehow ended up off-sync from my mouse which felt really bad, not sure what caused it (like if my mouse was on top of the game window in itch, inside the game the character was not in that exact position)
