Here is a 10 minute video i which Jonathan Blow explains how this game or one of these puzzles work and how the game teaches you that.

I somehow can not Embed the video but as you will see it really a great way how to "skip" tutorial text and explanations but let the game teach you how to play. He also said release will be sometime next year but I am not sure if this was really recorded this year or if we really have to wait till 2015 to play this game.

So it's basically Myst but with variations of line puzzles.

I do like the look of it - very clean. In some areas though there was no movement, no tree sway, no clouds blowing past, everything was so static I thought my video froze up. Later on you can see trees swaying when he's solving the black/white box puzzles so I'm sure it's just some finishing touches that need to be put on.
