The game randomizes your sprite, press R to change. I originally had the enemies spawn at random but when I added the eye as the main goal to win, I changed it to spawn mainly around it. Yes, you can float around the edges without much hindrance but if you want to win you will eventually have to go to the center where the longer you wait the more enemies you will face. I wanted to make it short and easy enough that most people would be able to finish. I wanted to add more types of enemies but unfortunately ran out of time. Thank you for the feedback and for playing!
