Cool concept! I feel like enemies should chase you a bit more, since they tend to stay near the screen borders and it makes it difficult to circle them.
Thanks for the feedback! The original plan was to have the enemies follow you, but we ran into a problem where if over 3 enemies grouped up next to each other, it became impossible to loop them. There's probably a way to alter their movement to fix that though. I'll look into it in the future.
