"The Unfinished Swan - E3 2012: Extended Gameplay" by Giant Sparrow
The player is a young boy chasing after a swan who has wandered off into a surreal, unfinished kingdom. The game begins in a completely white space where players can throw paint to splatter their surroundings and reveal the world around them."
This looks lovely!
