A compact, stylish arcade game that requires skill and attention. You control the beam energy, which passes through the walls. The farther you advance, the more treacherous pitfalls that you will need to overcome. Sometimes you'll need to collect keys to open doors. Enemies are the laser beams, balls, jumping from the walls, and sometimes even very walls themselves! At first it may seem that the first levels are easy, but as you advance you will get hooked!
