Hidden miniature worlds

A colorless, formless world is gradually revealed by interacting with miniature spheres found scattered around. Each one, a tiny world unto itself, when released, will fill the outer world with its influence.

It is possible to control each sphere independently and observe the combinations of effects possible under their influence. However, to suit traditional control schemes, this demo only allows moving two each time.
