Great use of the theme in the game idea, coincidentally I've just finished a book on Greek myths. Loved the gameplay, genuine fear when I heard the minotaur approaching and I couldn't find the way out of the area I was in.
Sometimes I didn't always get an audio cue for which directions I could travel upon entering a new area. Not sure if this is by design. If possible, maybe the could be sped up if the minotaur is near? Like the voice in the dark is fearful for your life and so is passing on the details faster.
Other than that, really fun game.
