I've played it for over an hour and a half. I haven't beaten it yet, but I also haven't noticed any serious problems with it. There is one minor issue, Wallace's female neighbor... When she moves her head in the game, there are some graphical distortions with the flower in her hair. One moves with her head while a "second" remains stationary. It's hardly game breaking, but when it's the only noticeable "problem" it stands out distinctly.
Sam: There's a book on the shelf over there. If I had even the slightest inclination to strain myself, I could probably relatively easily lean over and grab it. But I'm sure I can turn it into a meaningless puzzle of some sort.
