(This is an edited version of a review I originally wrote for my 2013 IFComp blog.)
The Challenge is a one and a half room demo with graphics which are stills from a simple 3-D modelling exercise. You can turn to face in different directions. There's a knife. And that's about it. If IFComp had a qualifying round, The Challenge would have been eliminated at that stage because the competition is not a venue for incomplete tech demos.
