You've spent the night at a man's house, only to find out he's suspected of horrific crimes. While he's in the bathroom, you have only a short time to discover the truth about him.
This is my favorite of the RGB cycle by Charm cochran, a collection of small games revolving around Bluebeard-like themes (secrets, murder, forbidden rooms). This one includes some really nice US design, with a text message-like interface contrasted with room exploration and dialogue that use different colors.
It includes a lot of exploration and a fairly complex puzzle. I played to one ending, which I enjoyed, but didn't feel compelled to try more. Really neat just how much love and detail went into a small game.
