For what it is, Escape in the Dark is fine -- a low-key, almost spartan, escape-the-room type game, done with style and a hint of atmosphere. The puzzles are challenging, but not brain straining, and they all make sense. I felt the atmosphere was a bit lacking, and the ending was just kinda there -- it didn't seem the adequately reward the player for making it through.
It's short and it's better than most escape-the-room setups; serviceable is what I'd say, and that's neither a slam nor praise.
