Help pilot the little yellow submarine through the perilous waters in the Cave of Doom, far below in the depths of the ocean. Press your spacebar to "bump" the sub upward, and release to let the sub move downward. As you move through the cavern, don't touch anything or your fragile submarine will sink down to Davy Jones' Locker! And watch out, because your sub picks up speed as you go along! GopherGas
