Terrible keyboard controls indeed. I'd read about this and it kept me from buying it for a long time, but I finally caved in during a promo sale. I started playing it at the time but ended up putting it on halt after a couple of days because I got really frustrated with the controls. The quick-time events are probably the worst of it, but even walking around feels... awkward. I found the mouse controls somewhat better (once you get the hang of them), but since you need the keyboard for the quick-time events you end up fumbling between them quite often, which only adds to the annoyance. A shame, really, because I spent more time fighting with the controls than enjoying the game.
I'll get back to it eventually, because I liked the story and would like to see it through, but I'm pretty sure it will take several goes because of this.
