So, I'm not too sure if its just that my PC is glitchy, but after you kill the guy in the middle (the closest to your spawn point) you can go straight through the wall at the bottom. Not that there's anything back there, as far as I've seen, but I've not even gotten past the first level, so I'm unsure

Thanks to everyone who made this, it's a pretty good game!
