You're a robot that's hopping around on a planet where you can eat delicious coins. Those coins, you'll have to earn them: avoid obstacles, bombs and ravines, because if you're hit too often, game's over.
You can play this game both with your mouse and your keyboard. If you use the mouse: move the mouse cursor to the left side of the robot to go left, move the mouse cursor to the right side of the robot to go right, and place the mouse cursor on top of the robot to stop. Press the spacebar to fire and press the left mouse button to jump. If you use the keyboard: press the left arrow key to go left, press the right arrow key to go right and press the left/right arrow key again to stop. Press the spacebar to fire and press the left mouse button to jump.
