The idea of the game is to guide Terry to his house through 12 levels of obstacles and adversaries. You have 2 choices of ammunition to fend off the relentless stream of creatures, your trusty Yo-Yo or stones that you find along the way. Some of the nasties require more than one hit in order to destroy them and some will have to be avoided altogether. After each round is completed you are placed in a Bonus level before entering the next round. There are some areas in each section which may only be entered if you have found a key. These are found, as are most of the features, by catching them having hit a baddie. Less
