Something is knocking, and you are not supposed to open up. This horror tower defense game turns everyday places such as schools, hospitals and office buildings into haunted battlefields. You choose a room, close the door, then level up your bed, door and heroes while summoning a defense line against monsters that crawl out at night.
Matches last about five minutes, so a round fits any break. The gothic chibi art mixes cute and creepy, with around a hundred stylized heroes and monsters and a wide choice of avatars and haunted locations, from a ghost-filled train to a dormitory echoing with midnight singing.
