Pusher likes to be alone inside his colorful block world. Use boxes to throw all the evil robots out.
Grab ahold of yellow blocks and push them around levels to destroy all of the robots. You will continue to move in one direction until you're stopped by a wall. Avoid touching robots directly and moving off the screen. Use blocks to shield yourself from spikes and lasers that would otherwise kill you. Avoid spikes, laser beams and robots. Use movable object as a shield against laser beams and spikes and as a weapon against robots.
