Nintendo just opened the site for the new Stafy DS game
and it just looks gorgeus! The 4th one didn't look that hot, plain 3D din't mesh that well with the flat 2D art, but this looks awesome.
We have all other games but the first, which is quite hard to get, but the Ms. has finished them all. Not bad for someone who basically hadn't picked up a controller before.
Based on gameplay, I get that this will have more costumes and more complicated puzzles and... co-op play! Finally a valid reason for the second, lime green, DS, eh? :D
