When you are on a level past 100- if you go to select a previous level you will be stuck with not being able to access all the chunks of 50 levels after the first two.
I know all these people are saying this game is trash and it kinda is. But if you want a future in game development put more effort into your games. And if you're going to put it on Knogregate never use scratch. Like literally everyone hates it.
