Road-Frog

Road Frog is a Frogger clone for the Tangerine Oric computers. It was coded by Philip Hulme and published by Ocean Software in 1983.

There is the road, the cars and the logs in the river to jump on. The 48K Oric version adds (on higher levels) both a snake, turtles and a crocodile, but still no way to jump back once you've jumped forth.
