A wonderful game. I particularly enjoyed the graphics, and the music felt really fitting. I found some of the distance backtracking could've been shorter. All in all though I really soaked up the ambience of that big, dying wood.

I consumed the seed of light and sacrificed the essence of man.
I think I may have broken the sequence somewhere. I blocked the river before seeing the dirt patch. When I went there it said "it's dry now". I imagine I could've gone there to grow the seed. It's good that it happens like that so it has replay value.
