The PC controls take a little getting used to, but they aren't that bad, and you can easily manually bind them to whatever keys you want by editing the config file, which they must have intended, since there's a specific config file just for key bindings. It's pretty typical WSAD keyboard movement, with mouse camera control.
My only gripe about the PC version is it doesn't support widescreen, and nobody's found a workaround tweak for it (yet.) Still though, it was 6 bucks. I've masturbated into bigger wads of cash than that.
