Graphics are pretty average. Just throwing that out there.
Looks like a generic dungeon crawler game, which isn't bad, but I already have decent alternatives (Ruin for the Vita, a whole crop of them for the PSP).
It looks like something that a Nintendo console has been in dire need of. I'm a real sucker for dungeon crawlers.
For a portable most of that stuff is new.looks pretty cool, although it's kinda funny how they are so excited about their random dungeon generation, massive amount of items, and scaling difficulty with people entering/leaving as they please since this is nothing new (been arround since 1996). Hopefully it'll provide a long fun gameplay.
