You find yourself and other characters trapped in a house over the span of five days. Part Laura Bow (isolation), part Phantasmagoria & Scratches (horror theme, backstory to the house) - it's a point-and-click game that's good for a weekend. After I finished it, I quickly downloaded the sequels to play through on upcoming weekends, as I enjoyed it that much.
