Your goal in this puzzle platformer based on the idea of shifting dimensions is to get in front of the door to proceed to the next level. Use LEFT and RIGHT ARROW KEYS to run left and right. Falling on spikes is sure to hinder your progress so press SPACEBAR to jump. The SHIFT KEY can be used to switch positions. In some levels you need to grab a key to rotate the lock. Too bad this game is rather short. Good luck!
