Quite long, as the story mode takes a while to finish, plus there's an endless mode where you play for high scores. Actually, gunning for high scores on each stage is also an objective, but a minor one. Im sure i've already spent over 3 hours on the 4s before, but when i transferred to the ipad i wasnt able to play much. Played about an hour today though, and it's still pretty fun and frantic. In endless modes, there are missions you need to fulfill to unlock more combo moves for the current character you are using. In addition to replayability, you can replay any story mode level as much as you want to earn money and higher scores.
I read on ign that Viewtiful Joe is coming in the next update. That sold me. I love all the old VJ games and am up for a swipe controlled beatem up. Henshin-a-go-go baby.
