Roc 'N Rope (1983)

Your player is a mountain climber who must avoid cavemen, dinosaurs and pterodactyls as he climbs up the cliff-sides. Your goal in each level is to climb up and reach a mystical bird with great plumage, while staying one step above the bonus timer which determines how long you may stay on each level. The mountain climber has only one ability; to shoot rope at 45 degree angles which he may then climb up to other platforms. His other action is a stun beam which will allow him to walk past enemies who get too close; but will only work horizontally from him. As for power-ups, on each level is (usually 2) a flashing diamond power-up which will make him invincible and allow him to defeat monsters. Also as a power-up are glowing treasures of some kind which are worth extra points.
