This is rather interactive animation than a real game, because once you click on the given option, the story moves on it's own without you needing to intervene.

Weapons are sometimes obvious such as a machine gun, chainsaw, while other times their are made out of an improvised tools and objects from everyday use, such as stool, so the deaths tend to get quite brutal. The game gives you this weird mixed feeling of quilt and questioning yourself and your own sanity because you might find this kind of brutality quite entertaining and fun. But don't worry, many people do...On the other hands I would keep small kids away from this kind of games, just to stay on the safe side.
