[pc] [2000-ish?] some kind of atmospheric free running simulator

I remember it was recommended on a youtube video about indie game or something.

But the premise of the game was you are running in like a forest or grassy field. Maybe it has multiple map but i'm not really sure.

I remember they mentioned, it is different from other running simulator because hitting into tree won't stop you in your track just slightly redirect you so you can continue running.
