Use the Arrow Keys or WASD to move. Press SPACE or Z to jump. Your goal is to get to the door without stepping into the light!

When the cursor in front of you turns green, you can press X to phase through the wall. You can point your cursor diagonally by pressing two directional keys at once! You can only move through walls that are covered in grass. Concrete walls are impassable.

In later levels, you can hop on switches to turn out the lights.
