Warp across screen: Stand inside the upper tunnel and continuously move
back and forth while partway off the screen. Your character will
eventually disappear and re-appear on the other side of the screen
after a period of time.
Extra points: Pick up a coin or other bonus and simultaneously lose
the last life.
Alternate exit: Clear all the coins from a maze, then lock the door
directly below the top exit. Run into this locked door from above
to freeze to it. Press Up to complete the level without
touching the exit.
