I just spent a very pleasant 35 minutes playing this to completion. I'm already familiar with the truth/liar logic puzzles and the stereoscopic images but they are always fun (you can actually do it with a computer keyboard if you try :)). I wasn't sure about the maze so I took a guess and was right (sic). Very enjoyable as I managed to pick four truth-sayers for the final challenge and slew the minotaur.
