* DummiedOut: In Kula World and Roll Away, the 9th hidden level [[note]]The one that says "VERY WELL DONE" in big blocks to anyone who finds it.[[/note]] and the tutorial level.
* WhatCouldHaveBeen: The developers were originally going to make a futuristic tunnel racer before Söderqvist suggested the game that ultimately came about. Also, jumping wasn't originally part of the equation and the ball was at one point going to be a mouse-type creature.
