This is my second game. Its a One-Button-Game similar to the Helicopter Game. You only need the left mouse button for controll.
Avoid the rocks and do not crash into the cave.
Be careful as every time you use your engine (press the left mouse) your Oxygen supply will be decreased. You can pick up additional Oxygen once you dive into a O symbol.
Controlls: Left Mouse Button
Symbols (to pick up in the game):
O : adds Oxygen
> : Speeds the Game up
R : Reverses the controll (mean ;))
S : Give you a Shield. Will only help you against 1 rock. Do not collide with the cave!
