Turtles

All while avoiding the bugs/cars running around the maze, you must also avoid getting caught by them or they'll stun you temporarily. When your mines are gone, resupply by passing over a star in the centre of the screen. However, beware - the simpleminded bugs become smarter as time passes; their colours will change.

In each level, you're on a floor in a house, and between levels you can see the turtle climbing to the next floor until it reaches the top. Note that in some versions, the kidturtles are replaced by people whom the turtle must save from ships, while the bugs are turned into turtle-eating fish.
