Crimson Room — About this game
Crimson Room on DS collects the Crimson, Viridian, Blue and White rooms. Each is a confined-space puzzle in which a small object or changed viewpoint can make an earlier clue useful. Examine the room, inspect items closely and test combinations before trying them on the surroundings. Start with the red room and work through visible furniture, then revisit edges or areas whose state has changed. Listen and read as well as tapping: escape depends on connecting clues, not on racing a clock. This DS collection uses its own room interactions rather than the PSP Reverse additions.
