An indie game to give you colour nightmares
Above is a video of gameplay from indie game The Unfinished Swan.
From the official site:
The Unfinished Swan is a first-person painting game set in an entirely white world. Players can splatter paint to help them find their way through an unusual garden. The game is still in development and no release plans have been announced.
This looks amazing, but is enough to give nyone nightmares of a colourless world.
