Well:

Best game made with 3dGS I have seen so far!
(From what I can tell from the demo)

Some really minor odds are offset by the vast majority of
grafical eyecandies and nice controlls.

I would really know how you have made the terrain.
Is that a Model, a Terrain, or Blocks?
I shure cant tell! It looks amazing.

Just one addition: the movement of the playermodel could
take a bit more time to turn, and "drag behind" a bit more.
