Description (written by the developer; not a statement by this register)
Storyline: Stuck in a flooded, abandoned mental hospital your mind deteriorating as your happiness descends into darkness, you always get an eerie shuffling sound outside your room every night at 9:00 pm but you are alone why would anyone or anything be here. You get progressively worried so decided to look through the peephole. You see a smiling faced creature with a tall and skinny body staring at you. Next night at 9:00 pm you investigate and find out these occurrences…. Credits: Scope and Mi-Violet Core for some OSTs Bousi for AI
