I've watched a few videos and I still can't tell what the purpose of the game is. I just see a guy running around really fast shooting at trees. It looks like a very pretty, large, empty world. And that hard-rock techno music on the videos is just annoying and doesn't seem to fit the style/theme of the game.
Considering I've never heard of it before and after watching videos and looking at the website I still can't tell what it's about, I think I'll pass.
