Hue was a free Indy game that was available to download one PSN.
I finally got around to playing it. I've had a few mental months with life, and some of these puzzles took me a while to complete it !
It's been a while since I played a game that really made my brain hurt. I haven't had those feelings since portal 2 multiplayer.
The slow-motion scrolling through the colours were really satisfying and I loved the silhouette style, reminiscent of Limbo. (another indie favorite)
I thought that the walking/traveling element, while it told the story was a nice touch, and also stopped people from skipping the story line.
