It looks like D3 is getting inspiration from the series of Crimson Room flash games because the Simple Series Vol. 27: The Misshitsukara no Dasshutsu has a similar premise and budget look. You play as the protagonist from The Suiri (cameo alert!) who is thrown into a house that you have to escape in traditional adventure game style. That means poking around the touch screen to search for keys and thinking outside of the box when you can’t find them. The difference between this and the DS Superlite port of the Crimson Room is D3’s game is brand new. Also you’re escaping out of a house instead of a room, which suggests there are going to be more puzzles in The Misshitsukara no Dasshutsu.
