This is really cool! I was jumping around collecting jumps, I had about 200, then I think I broke the game jumping up from the main screen. I jumped up and then went right past the "goal posts" on the bottom of the screen, and it didn't re-spawn me or move me to the lower screen. But I kept falling, because no matter how much I spammed space all my jumps weren't enough to get back on the screen by the time I realized what happened.
