In this game you have to swing around on a rope and interact with various pegs dotted around the stages as you try to collect jewels and avoid diamonds (the shape, not the jewel). Just press the mouse button and the cat repels and swings from the stretching rope. On some levels it becomes necessary to move the fulcrum to another peg, by pressing a key (any key will do) just as the rope hits a peg, as the entire play field for a level may be much larger than the game window. It is in this way that you can make your way around the level.
