Jim Sterling did a pretty good let's play of it, that also highlighted a lot of the problems with the PC port. But there's a mod out that's supposed to fix a lot of the problems.
There don't seem to be any branching choices, and the plot is very Twin Peaks-esque.
I loved Alan Wake which I heard is supposed to be Twin Peaks like as well. Never saw Twin Peaks though.
