Ride in a submarine through an underwater trench to get as far down into the ocean as you can! Use the mouse to steer your submarine through the trench, hold down the D key to turn on the submarine's headlights. Also, try to get the coins on your way. And dive as far down into the ocean as you can! How deep can you dive?
As you go down the trench, it gets darker and harder to survive. This game works better in full screen.
