|The balls with monkeys living in them return! Less arcade-y feeling as you can save every ten stages and can restart a stage an infinite number of times (seemingly). I've heard it said that the stage design is less inspired than in the first game, and there seems to be something to this assertion, though the early stages make use of more moving elements than the early stages in the first game, which can lead to some fascinating experiments with the game's robust physics engine. Indeed, the real plus side of the unlimited continues is that you can spend time just doing wacky stuff, though I suppose in the first one you could do that in practice mode.|
Lots more mini/party games this time around, incredibly enough. If you got four people and four Wavebirds and SFMB2, you gotcherself a party. Maybe the single-player doesn't feel quite as true to its arcade action roots as the first game (there's, like, a "story" and cutscenes now too) but there's still more than enough here to love thoroughly.
Supports progressive scan, unlike the first.
