Blue Chamber is the latest of the “escape the room” puzzles by Toshimitsu Takagi of Japan. The object is simple. You wake up in a room that you must escape from. The means for escape are in the room, you just have the click around the room to gather what you need. It’s simple, but very addicting. You may want to try Crimson, Viridian, and White Rooms first, since this is a little harder than those. If you need help, go to the hints page for a link to a walkthrough.
