Since I was running out of horror games to play in the Internet Archive, I decided to broaden my sights by exploring the Interactive Fiction Database. That is where I found Faithful Companion (2013, Matt Weiner).
Faithful Companion is simply but difficult. You are at the cemetery, visiting the mausoleum. You want to get in the crypt. Opening the doors that lead into the crypt should be easy except you are being followed by a ghost. Any action you take will be duplicated by the ghost two turns later.
That may not sound like a big deal until you learn that, if the ghost touches you, you will pass out. If you take something and are still holding it two turns later, that means the ghost will take it from you. If you have to open a door by pushing three latches so that they open, the ghost will follow behind you, pushing the latches closed. The game’s challenge comes from fooling the ghost into helping you accomplish what you want to do.
I enjoyed this game. It is short, it is not impossibly hard, and it’s rewarding when you actually figure it all out.
