And each section requires you to fulfill objectives, like taking down a certain number of baddies, collecting more objects than the other players- EVEN BOSS BATTLES- while staying ahead of your opponents. Point-acquisition is the main objective of the game, and whoever has the most amount of points in the end is the winner.
