Dreams has a short single player campaign which is designed to showcase what's possible, and in this new Game Informer gameplay video, co-founder Mark Healy shows a playthrough of the stage (which is great – we played it a couple of weeks ago) and then switches to edit mode to prove that it was all made in-game.

The amount of features and functions are just flabbergasting; at one point Healy adds an 8-bit filter, and it all just… Works – without any loading. We’ll let you watch the video for yourselves but… Crikey! This is insane.
