Frogger meets Pacman. In part one of this game you use the cursor key to guide Thomas Frog from bottom to top of the screen through a maze of slowly moving barge-shaped barriers.

Master this and you graduate to more advanced problems. Once again you have to climb the screen, but this time the maze takes a different form. It's not

unlike a Pacman maze, which slowly narrows to make it harder and harder for you to gobble up the power points which are dotted about.

This second stage is really quite difficult, and your admittedly less than nimblefingered reviewer came nowhere near succeeding, so there's enough challenge to ensure the game's appeal will last.

Points are awarded during each part of the game, and a highest-score record is kept.

One particularly nice feature: you can examine the Basic program in order to make your own improvements, and each maze can be saved as a separate game.
