I like the aesthetic and visuals. The music pairs well with it too.

I am a bit confused about how to play though. I would like it if the instructions were more clear, or maybe they popped up on the "Game-Over" screen because I am quite lost.

There is also a bug with the scroll wheel, it takes it as a bunch of clicks.

I like the cute animations! Fun. I found it frustrating not being able to go full screen, had to constantly scroll to find the baddies. But other than that good job!
