This is about the best proof I could get. The attempts counter is wrong, I just restarted the project at some point. This took me about 30 - 40 attempts to beat. I didn't use secret ways, but there are some. If you make a wall at the end, over where you are supposed to go, and make a big ceiling connected to it, people can't get through. I noticed 3 secret ways by just going to the borders at the top. The borders don't actually have any collision, they are just for show.
