In the game you control a hero equipped with a switch hook. This fancy device lets you switch places with monsters dealing them some damage on the way. When there are few monsters on a level and they are weak and slow, you can use the hook like a ranged weapon without much thought, but later in the game you'll need to choose a right target each turn and use walls, columns and passages to avoid enemies' attacks. There are 20 tiny levels and 8 types of monsters in the game. All monsters except basic "undead warriors" have some uniques features, for example some of them can't be damaged by the hook and others explode when they die.
