Think you've seen weird? You've seen nothing until you've spent time in cube-face mouse Gregory's hotel for the incurably deranged.
You play an unfortunate kid who stumbles upon Gregory's place, where twelve bizarre characters wander the corridors, carrying their souls in milk bottles. The only way out is to steal their souls and deliver them to Death in your dreams. Y'know, that old chestnut.
With the assistance of a friendly zombified cat called Neko, you must creep around the hotel, peeking through keyholes and hiding in closets in order to learn the weaknesses of each resident. The movements of every character are recorded in your diary, so you know where they'll be at any given time. Important, because after gathering a soul, its angry former owner will be after your mental health from that moment on. If they catch you, they subject you to a frankly quite disturbing horror show, leaving your character trembling and half mad.
To reveal too much here would be to spoil the surprise, which is most of the fun. Suffice to say, you really don't want to get cornered by the likes of syringe-toting lizard nurse Catherine or the lunatic robot Judgement Boy more than once if it can be helped.
This is nothing short of survival horror plus time-based puzzles, multiplied by a liberal dose of Japanese madness. Although it looks simplistic, the chills and thrills are far too good to be dismissed as kiddie face. Check your sanity at the door, and take a long vacation at Gregory's...
