Your objective in this puzzle platformer is to reach the glowing blue crystal in every stage by using common gaming items such as doors, buttons and springboards. The main tool of choice is a door. Doors with identical numbers are connected to each other; walk in one and pop out another, along with whatever you were carrying. This fun game treats doors as items like any other, meaning that you can pick them up, use them to activate switches and so on. Use LEFT and RIGHT ARROW KEYS to move around. Use "S" KEY to jump, and use "D" KEY to pick up/throw objects. Good luck!
