This is how it is. You have two heads, which are connected by a chain that can be extended. One head walks and the other follows, and your goal is to climb and fight your way through levels with sticky walls, spike traps, and all kinds of monsters trying to hurt you.
All the time you have to adjust the length of the chain, and change which monster pulls.
But that’s not all. To make it even more difficult, the green head can only knock out green monsters, while the pink head vice versa can only crack the pink monsters. Everything is controlled with the arrow keys and is a superb combination of climbing action and brain gymnastics.
