At the top is a ledge on which Ollie chases the girl, occasionally knocking down flowerpots that may hit J.J.
Holding the button down allows faster movement, but speed can be used only for a limited time as shown by an on-screen gauge.
If Ollie is hit, he falls down and the level is complete, with bonus points awarded for each flowerpot remaining on the ledge.
A monster named Sneaky Pete occasionally climbs out of the pit and wanders across to the start button, stomping on it, which causes the parts of the machine to fall off of the blueprint.
Some of the creature names are different in the C64 version: Fuzzy Wuzzy was changed to "Maze Monster" and Sneaky Pete became "Weird Willy".
