Cosmic Saucer Battle
A first person space shooter.
The Black Lagoon
As you move through the maze, your boat takes on water. When you enter a new area, you can press the trigger to empty the boat, but be sure to move on before the patrol boat catches you. If you take on too much water, you sink.
Hint: move diagonally when possible.
