Leap-Frog

Description
Leap-Frog is a 1-player Frogger clone for the BBC Micro.
The player must navigate their frog across a busy road and a dangerous river to reach the five holes in the riverbank at the top of the screen. The player moves in the cardinal directions as cars, trucks, logs, snakes, and turtles move horizontally across the screen.
Turtles will intermittently submerge, posing a danger to the frog. Flies sometimes appear in holes, which can be eaten for bonus points. Dangerous birds sometimes appear in these holes, and prevent the frog from reaching safety. Snakes cross on the river bank between the road and the river on higher levels..
The player starts with three lives and, after safely placing five frogs in holes, the player encounters a faster-moving level with more road traffic and fewer safe spaces to cross the river.
