A fun game for the One Piece fans.
The game takes place during the East Blue Saga (Captain Morgan Arc up to Lougetown Arc). You play as Luffy, with all of his Gomu Gomu abilities as attacks. You also have your basic punches and kicks. The moves can be tricky to perform and it takes a lot of memorization, as the instructions to the abilities are only shown in the instruction manual.
There are several locations you play in and each has three levels. The first level is getting from point A to point B defeating any pirates or marines along your way. The second level is the same as the first, only you fight a mini-boss at the end (Helmeppo, Mohji, etc.). The third level is a boss fight (Morgan, Buggy, Kuro, stc.). The bosses can be quite challenging and take a few times to defeat. You also meet the other crew members along the way and you can summon them during the game to help you.
There are very few edits. For all I know, the only edit is Zoro being called Zolo. There might be others but I haven't seen them.
All in all, if you are a One Piece fan, you will enjoy this game. If you aren't a One Piece fan, you might not enjoy it as much.
