Hello gamers! 
A game called Hue is currently free for a short time, until the 9th July.
Store Description:
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.
