Basically the objective of the game is to gain points by just doing whatever you can do in the game. Eating, stretching, whatever. Gaining points and submitting them to "Girl" (a large character similar to Noby Noby Boy) causes Girl to stretch to other planets. This unlocks new environments for you to carry about all of the wacky tasks you can do in the game.
The game is $4.99 on the Playstation Store right now, it's really pretty fun.
