Atmospheric and creepy, the set design and camera work are brilliant. The cuts between two concurrent situations and the boy's confession story playing out really help to build suspense. Missing proper jump scares or, at least for me, a sense of fear for the viewer, this falls into the thriller/slasher school of horror. Disgust, foreboding and disturbed are the emotions this short evokes. If you hate mould, slime and either of those on people, this will creep you out too.
