retrobits wanted to play Laserix 2 again on his b5.00 M33 Slim, so he decided to update the port using the Pheonix Game Engine and added many new levels.
Laserix is a laser that should go through all diamonds on the grid. The only way to do it, is to use mirrors, in the right position and adjust them to define the right laser path.
