Just a common Worm AKA Snake game, not really a 3D.More like two and a quoter or and a half D. You can't control the speed, only the direction. Eating fruit gives your points and makes you grow longer. Hitting a wall or yourself makes you die. Happy eating.
Navigate your submarine around obstacles in strong rotating currents to plug the nasty giant holes in the Mediterranean sea bottom. In case you are wondering, it is you, Harry Stamper, on the picture. Don't let it happen to you!
