Maybe helping a flea to escape from a monster in a pit is not your idea of fun, but that is what you are asked to do in this game.
By using keys one and zero, you hop the flea from shelf to shelf until you reach the surface, then try to avoid a prowling pterodactyl.
Instructions are minimal, just describing which keys should be used.
However, the program runs fairly smoothly with colourful, if not terribly exciting graphics and it is quite difficult to get right to the top.
During loading, you are confronted with messages, and finally see your approach to the blue planet over the title page, which I thought was rather well done.
As for lasting appeal, I am not so sure. The absence of skill level and high score facility make it a nuisance for two players to compete.
The whole idea seems to be aimed at the younger player, and I don't mean that in any patronizing way - it isn't necessarily a bad thing.
