Below is a video quickly demonstrating most of the levels from GhostWriter so far. They are obviously not complete yet: please ignore the UT hud (that's not meant to be part of the game). Also, the sound quality of the 'Corridor + Ballroom' segment is quite poor so ignore that also!
The missing levels from this video are the Kitchen (where the Muffin Man is located) and the front of the Crooked Mansion. These may be uploaded soon!
Alot of Kismet was needed to create these levels. Tutorials on how the Kismet was setup are also in the works. Here's some examples of how complicated the Kismet got for the puzzles to work within the levels.
