Floating in the void...
I recently finally got around to playing Bastion, and I was really taken with the way in which the ground rises up to meet the player character as he moves through the world. So much so that I thought I'd try my hand at recreating the effect in Javascript, with the results that you see here.
Move the character around the environment with the arrow keys. Ground tiles rise up from the void as the character moves, and objects fall from the sky when he gets near.
