You spawn in a circular arena with a laser cannon in the middle. The first shot will be directly upwards, and will subsequently follow your position (it will go to where you were last time). The lasers move around and shoot (denoted by a white line around the laser meaning it's active). You can drag the square around between the times when the lasers are active, your job is to find a spot where you're safe during the lasers shooting. As the game progresses, more lasers spawn. Each time a laser spawns, it's first shot will always be directly upwards, so avoid going there at all cost. The game also gets faster, so you must move quicker to find a safe position.
