Trivia

 * Gravity and mirror are the only options not available to begin in a custom level. But gravity can still be changed from start position.
 * By entering a Form Portal that is used to transform you into the same form you were in before entering, you can shift the playing area either higher or lower, as long as the second Form Portal is place higher or lower than the first one. This trick is used to enter the alternate route for the third secret coin in Stereo Madness.
 * The size portal is the only manipulation portal that does not use blue as a deactivation portal, instead it uses green.
 * In this small form, the cube and ball forms are manipulated by changing the detail from its original form to one that resembles the very first type from their icon kits respectively.
 * All portals (except the speed portals which are not three-dimensional) have an effect in the Level Editor, where only a part of the portal is shown.
