I just played through CV III from start to finish in one sitting on Halloween, for the first time in years. Yes, it's incredibly frustrating at points, but still a fantastic little game, with all the atmosphere, music, branching paths, etc.
I have to confess that I died a quite a large number of times on the final level, though. I also died in obnoxious bat, stairs, and pendulum situations more than I'd prefer to admit.
