Tubular!

Collect 14 bells and make it to the top of the pyramid before time runs out. The pyramid has fourteen floors, and the only way between them is through high-pressure tubes. Walk left and right along a floor; walking under an up tube carries you up a floor, stepping onto a trap tube drops you down one, and walking over a bell rings it. The fourteenth bell opens the tube under the peak, and going up it finishes the level and earns an extra man. Each level gives you 120 seconds; when time runs out you lose a man and start the level again from the bottom with all its bells. There are sixteen levels, and you start with three men.

Controls: The joystick on either controller walks left and right. A button starts each level and each new try. On the title, up and down choose and a button confirms.
