This is an original platform game. You are some kind of rodent called Gyro Atoms. You must reach the end of the level without falling down or being killed. You move left and right and duck with the arrow keys. You jump with Z. To jump higher, press Z together with the down arrow. You can also shoot atoms. Press and hold X to display an aiming arrow. When the arrow shows the right angle, release the X key and throw an atom in the current direction. Gyro Atoms can bounce off the walls and perform some other cool tricks.
