Hahahah, I glitched out level 1 so bad, the mechanics in level 2 didn't work. if you want to pull of this glitch, you have to complete level 1 using only one player. Hope for the best and try and reach the door. once you get to level 2, the buttons won't work, and the ground won't work either. which will sink you to a pit that you can't get out of...inside the rock.
This is a great game if you want to pull off some fun glitches, but a terrible game if you actually want to complete it.
