Too many extraordinarily long cutscenes, the subgames are generally not fun at all. In some, you can get stuck without any clues as how to continue. Exiting from games when you're done takes way too long, and the gameplay itself is frustratingly poor.
Should have stayed with mini games that were actually fun. This title could've been a contender with the warioware series. Only had the game for one day before returning it in disappointment. Come on Ubisoft! I know you can do better than this steaming pile of manure you call a game.
