Low budget horror. You can spot it by the cardboard sets and the clumsy effects. But that doesn't matter. Story is good and so is (most of) the acting. Only problem I have with it is that the solutions are not within my reach to find it satisfying. Nobody can figure this out, so it's pointless. If only the riddles were more doable, it would have been a great film. Now it's a good film.
