I rented it but got stuck (as in no idea what to do stuck, not can't beat a boss stuck) in the last dungeon.
Anyway, my problem with this isn't that it's not revolutionary or the graphics look bad or I think there's anything wrong with SNES-style adventure games or with one person spending five years on a game or anything like that. I think if you create all the details yourself, even if you don't make any radical departure from existing game conventions, your personality will come out strongly in the final product, which is interesting in itself. The problem is I get the impression the guy has a fairly unpleasant personality, and I don't mean his Aspergers or whatever. e.g. the guy in the first trailer who's supposed to be a pacifist I guess.
