You are the robot who is on his way to search for the kitty. Use the arrow keys to move your robot. Try to collect as many power ups as possible. If you die, 20 seconds will be added to your total time which will reduce your score. Kill aliens to subtract 1 second. Hit the z key once to make a jump, and again for a double jump. Hit the X key to shoot lasers. Double tap forward to zip. Down + z fires the rocket upwards. Collect red blue and green keys as well to unlock doors and other mysterious effects. Rescue the kitty and clear all levels.
