Le Fil is a game about a guy -- a creature -- a thing -- who falls from the sky into an unknown world. His goal is to return, however, to do this he must reconstruct an ancient tower that rests in the center of this world by gathering shards that once belonged to it.
You can find the alpha demo here. It's a bit heavy so you'll have to excuse us for that. You'll also need the 3DVIA Player plug-in. Or you can just watch the video above. I recommend watching it in full screen and 780p.
