Does look like they're trying new things with this game, which is to be applauded. The dungeon items in a 'very important shop' is quite interesting, does seem to point to completely re-thought gameplay. I also wonder if it means you can tackle the dungeons in whatever order you want, as long as you 'borrow' (?) the right gear first?
I guess it's a bit easier to understand spare arrows and bombs lying around the place than infinite ammo that appears out of nowhere (ok, magic). But fair point I suppose, can see both sides.
