Arrow keys to move and jump. Click (don’t hold) space to shoot your laser cannon, and do not do this more than three times in a row. Collect the panels that fall from the ceiling or floor, depending on the gravity, do not shoot panels or they’ll explode. Use your laser cannon to destroy flying robots. The gravity LITERALLY flips. If you get stuck at the edge of the screen, jump and go right. Do not go to near the right edge of the screen, that is where enemies come out.
This game was originally my dad’s idea, but I built onto it to add falling panels and your weapons.
