Oh yay! Hue [official site] is coming out soon. It’s a puzzle platformer where you swap background colours to conceal and reveal bits of the environment. I saw it at Rezzed maybe the year before this so I’m excited to see how it’s ended up.
Looks like we’ll find out on 23 August when it releases. Oh, and there’s apparently also a colour-blind mode which makes use of symbols instead of the colour wheel.
