If you manage to stamp something else than the paper by releasing at the right time as your moving over and away from the paper, the game crashes.

This was the heaven stamp. The exact same thing happens with the hell stamp, the only different thing is that everywhere it says heaven on the error message is replaced with hell. Sorry that im a little late replying. Not the best person at checking my notifications.
