Izuna: legend of the unemployed ninja.
it was okay, but not enough depth or complexity. I wouldn't buy the next one, because I think they're just adding more work instead of fun, to be honest.
I get annoyed when these sorts of games seem to replace complexity with cheap tricks to make the game harder.
I guess I really just want a good ol' graphical roguelike for a change. God, if someone had a I.V.A.N. or T.O.M.E. or netHack or even Dungeon Crawl on the Ds, I'd be a happy man.
