Thank you. Most players seem to have a hard time focusing the laser on a certain location. Whenever the laser is on, the cursor will stay still relative to the world not the screen if you don't move the mouse. This means, you can put the cursor on a light sensor and keep the mouse still and the laser will always aim at it no matter where you move. This technique is very useful in level 4 and 6. I am working on finding a better control scheme since this seems to be the greatest barrier facing most players.
