True, but I like how impressed he is by certain parts of the graphics/meshes :) The procedural generation technique, apart from saving tons of space, also allows for some pretty good+realistic tree trunk and rock objects (or "effects" as they'd be called if this had been a regular demo instead of a game).

I do agree with him about the lack of gore. It doesn't necessarily have to be bloody per se, but there's a great short gamedev presentation called "Juice it or lose it"[0] with loads of basic little tricks to make a game "juicier". They already hit a bunch of them, but there could have been some monster bits flying from the explosion.
