Your task in this puzzle platformer is to reach the portal somewhere inside the level. You can move between layers that make each level. As you switch between them, one will become the active layer while the other will become transparent and passable. It is all up to you to find out what you should do to get to the exit. Just be careful not to switch into solids. Use the ARROW KEYS to move. Press SPACEBAR or "D" KEY to jump. Press "A" KEY to switch between the layers. Use "S" KEY to pick up an item. Have fun!
