Use WASD or the Arrow Keys to move and jump. Click on a laser bulb to select it, then click a second bulb to draw a laser between them. You can move on top of your own lasers, but don't touch the beams of fire!

You can only deploy a few lasers each level, which are counted by the number of triangles in the top left corner. If you run out, press X or click the red X button to remove your lasers.

When two lasers cross over each other, it creates a new bulb, which you can use to make new paths. You can also create a path while you are moving or jumping. Click and hold on the second point, then release the mouse button after you jump to create the path while you are in the air.

Keep creating new laser paths to reach the green finish marker!
