Hello, thanks for feedback. Yeah, the game gets very easy once you get the controls and how it all works, it was not intended to be too challenging. For enemies, I actually have a function that deletes them when they are far behind, but I believe you're right about adding some kind of spawn limitation for them as well. even though if you complete it with a normal pace, there shouldn't be many enemies around, unless you're standing still.
Thanks for playing :)
