NES- Back to the Future

In the single mode game, the player controls Marty McFly through various stages set in 1955 in which he collects various clock icons in order to advance to the next level, and avoid the gradual vanishing of his future (indicated by a fading photograph at the bottom of the screen). If the photograph fades fully, Marty would lose a life as it would show him vanishing. Collecting 100 clocks restored the photograph to its full, unfaded status. Two power-ups can help improve Marty's control: bowling balls that can destroy enemies and a skateboard which can speed up gameplay.
