Yeah, I noticed that the level design wasn't that great. This is probably because I wanted things to line up nicely when doing it the intended way. I considered adding a star system like some mobile games do, but I didn't end up getting around to it. Might add it as an update to help with cheese, but don't get your hopes up.
Edit: I don't think there was a level called "loop around". Only thing I can think you meant was level 6, where I wanted to make another upside-down level. No looping intended.
