That's very interesting indeed, I was thinking it may have been inspired just because of the way the movie shifted from black and white to color.. the game doesn't quite do that exactly but it had enough parallels that I thought it might have had some influence.. the lost love, the internal dialogue ..
Either way it was very fascinating.. I especially like how the music audio sounds so odd and creepy when you shift states .. one state is vibrant and the other is murky and dark.. it's well done.
I'd love to see more of it :) I downloaded the source, I'm going to setup unity and hopefully learn from example on this one ..
Short, sweet and fun .. the only thing I had to get used to was the mouse speed being so sensitive
