Here is the gameplay trailer from the Gamescom 2015. It's not an article about GD or whatever, but I found the level design really interesting. Even if they show a way to end the level, I'm not sure all the players would played it the same way. Nicely done.
Seems like a promising game.
In Unravel you play as Yarny, a tiny new character made from a single thread of yarn that slowly unravels as you move. In this physics-based puzzle game platformer, you have to traverse nature's obstacles inspired by the breath-taking environments of Northern Scandinavia.
