Back to normal ZX81 graphics in these two cassettes from Unicorn. Firstly, Bears, which resembles a maze-type arcade game. Your task is to assist the last remaining grizzly to get as many of her cubs as possible, and provisions (in the form of honey) to safety in a cave. As the bear moves through the forest collecting honey the cubs occasionally become lost and have to be rescued before hunters, who roam the forest, reach them.

Instructions can be called up at the start of the game, which at first sight does seem to see it as a maze-type game - the trees being the maze walls, hunters being ghosts, and so on. Care needs to be taken not to get the bear trapped at the edge of the forest between her cubs and the trees. Action is reasonable at the faster settings.

The game has some nice touches, the player can define his/her own movement keys, the skill level can be altered to any one of six levels, and there is a hall of fame to record the best score.

The second release from Unicorn is Climber. Also similar in some respects to a maze game, but perhaps better described as a computer version of snakes and ladders. "Plasma bolts" and "guardian droids" are out to get you rather than snakes, and there are power batons to collect as you climb to the top. Like Bears, there is an option for control key redefinition, and speed and difficulty can be set to any of nine levels.

Both Bears and Climber are reasonably good games.
