Use the left and right arrow keys, or A and D, to maneuver Sanik around and use the space button to shoot a laser to eliminate enemies. You cannot let them come into contact with the ground, or with Sanik, and with each one comes a penalty of a deduction of a life. After seceding a score of 10 points, a golden coin appears. Shooting or coming into contact with it doubles the size of your projectile. Moving will make you a bigger target.
