A game called Hue is free to own forever.
As long as you claim your copy from Steam before 17:00 UTC on the 8th June.
Hue is a vibrant, award-winning puzzle-adventure, where you alter the world by changing its background colour. You explore a dangerous grey land, unearthing coloured fragments on a journey to find your missing mother. As obstacles match the background, they disappear, creating new and exciting puzzles - full of peril, mystery… and colours unseen.
