crimson room sequel
The third in the eerie and challenging Crimson Room series by Toshimitsu Takagi has been released. Each of these flash games involves being stuck in a room of a certain colour (crimson, veridian, and now, uh... blue) and using the items hidden in there with you to escape. The newest, "Blue Chamber", is much shorter than the others, but it's still fun. If anything, it'll be a good warm-up before you try the first two games.
