It's good horror. It takes pretty much no time at giving you reason to feel endangered, and the feeling of dreed keep only growing while each second passing and one begin to get's the idea what exacly is happening.
The only things that keeps it from being in my opinion perfect expierience is limitation (Kind vague questions to player and complete lack of player interaction.) that was set by jam this game was submmitted to. As after playing I was left with lack of closure, like the story stoped as it was pretty much as it started.
So I conclusion it's good short horror. Sure is creepy and all, but really feels more like a demo or set up to something bigger than stand alone title.
