This is the first Super Monkey Ball game that uses Worlds rather than difficulties. The game has 12 different worlds, and each one is unlocked by beating the previous world(s).
In the game there are 2 levels with secret goals, and getting both of them unlocks world 11. After getting these secret goals, you need to collect 2006 bananas in total to unlock the final world. Getting these 2006 bananas would most likely consist of "grinding" on one stage with a ton of bananas to collect. This doesn't sound like the most interesting thing in the world, but the rest of the game would make a very entertaining run, I'd say on par with the gamecube versions of the game.
Any suggestions on what kind of movie to make of this game? Or maybe if trading time for entertainment value is overall better for the banana collecting part?
