A Space Invaders style game with a submarine.
In this game, the submarine is the firing station and it can be moved laterally in order to reproduce the concept of the famous Space Invaders. The martians are replaced by crabs. Various parameters can be set using the eye-catching interface : 3 skill levels (each with a different number of crabs) and the speed of the submarine (the default setting is so fast that the player doesn’t have a hope !).
