Help a small robot recover his precious Gold Gear. Travel through four worlds on your quest, collecting silver gears along the way. Move using the left and right arrow keys, and press Spacebar to jump. Use the up arrow to access the robot's jetpack. Once you're in the air, the arrow keys will guide you around. Your jetpack requires energy, which will slowly fill up in a bar on the bottom of the screen. If your energy runs out, you will crash to the ground. Avoid spikes and monsters, which will kill the robot.
