Essentially I draw the very background elements: the rainbow-y one, the stars etc (which are transformed by a script according to the camera to give the sense of depth) and then all the game elements, text & the bubbles in the background just write to the zbuffer (so essentially invisible) and finally the pinkish morphing ‘void’ is drawn where it can (ie: not where the otherwise invisible bits are). As everything has different parallax it creates a weird atmosphere.

Any other question feel free to ask me at paul@secret-lunch.com

I’m really interested in non photorealistic rendering techniques in games, and I’d like to ask you about how you made this game and what techniques you used to get this gorgeous style.
