Short but sweet, the best Swedish Ghost Simulator. The youtuber 3FS (who I discovered it from) played this recently so hopefully it'll get the recognition it deserves.
Some feedback is that a fair number of youtubers seem to think the game only has one night. I think a level select would be a good addition, since it might let people know there's more to the game and you need to reply the entire (short) game to replay levels.
