The Doors to Constantine is an atmospheric exploration game where you explore a person's thoughts. You walk through rooms, each with a diary entry from Constantine in them. This is the first and so far only game by Wyre to have an original soundtrack, which you can download for free on the Game Jolt page. This game is very short, and should only take ~15-20 minutes to complete, assuming that you take a minute to read all the diary entries, etc.
