Inoffensive 2.5d platformer that doesn't do anything great, but does nothing wrong either. Character move-sets are pretty fun at least (Sanji has some nifty air-combos), but boss design isn't that stellar.

Skypiea could get slightly annoying if you didn't have Luffy to save you from pits.

As for the story, there's some treasure, One Piece villains are after it, including Crocodile and Eneru for whatever reasons. Then there's giants, I got the gist of it but neither Spanish, German nor French is my strong suit.
