A machine-code version of the arcade game, you have to move your frogs safely across a busy road then over a river, using turt1es, lily'pads and logs as stepping stones. But watch out for the crocodiles!
Though instructions on how to get into the game are displayed, the rules are not clearly stated, and knowledge of the arcade version seems to be assumed. The instructions state that sideways movement is via the "<" and ">" keys. But both of these are shifted characters, and "." and ",", the unshifted versions of the same keys, work just as well.
Reasonable graphics, considering the low resolution offered by the 2 x 3 pixel screen, but you really need a sound box to take advantage of all the effects.
