I tried out the, er, trial. The combat gets real in a hurry. It's really well done, except for the scrolling getting jerky way too often (which was an unexpected disappointment). Games like this should never have a problem with that. The narrator is not annoying at all, at least through the trial segment, which takes you from awakening to a sort of hub area. If anything, the narrator adds interest to what's happening, and a fair bit of humor.
I will be getting this eventually, I'm sure. I'm involved with something else at the moment, and I want to get a bit more feedback on Bastion.
