Sony's announced a new PSN exclusive, The Unfinished Swan.
Developed by Giant Sparrow, which says it's signed a collaborative-style deal with Sony similar to that of thatgamecompany, the game's described as a "first-person painting game".
It explains: "You throw globs of paint to explore the world around you. In the game, you're a boy named Monroe who's chasing after a swan. The swan stepped out of a painting and has wandered off into a surreal, unfinished world."
It adds: "We made a game about creating a sense of wonder. Our goal is to give players strange and beautiful experiences they've never had before.
"We want to give people genuine surprises, and then keep on surprising them the whole game. The painting a white world stuff is actually just the first 15 minutes. After that, things get really weird."
