Hard to Say there's any fault in this. A great little satirical look at the somewhat prolific game "The Witness". Run time for me was approximately 1 hour, but kept me well entertained and engaged for that time. For friend or foe of "The Witness", and at a price of free, this is well well worth the play, but I can't give it higher than a 3.5 because it's little more than a big gamE.
