A Very Fascinating Game, Well Done!
I applaud you, my good sir, for making a very unique game. This one has been one of the more interesting games I've seen; very artistic, very calming, and very intellectual. The way that the terrain required the manipulation, combining both 2D and 3D successfully in a game, the musical choice... Bravo, my good sir, bravo.
I will say that there are a few things that are off, but for this game, I believe that the graphics are just as they should be! It's a game about simplicity, so the graphics should match the meaning of the game. And with it being "the price of being special," the 3D is where it needs to be as well: nothing really special, just the change from basic 2D to 3D. This is how the game needs to look in order to convey the message.
The problem that people would probably seem to have would be manipulating the 3D shapes around, but that's strictly user-based problems. For what I could tell, the pieces flowed smoothly and were easy to maneuver, once you wrapped your head around the concept of it. It's not one that's too different, where it can be seen in many games on consoles and hand-helds. And the rolling physics were correct as well. People complain that they can't move in the air, and end up just pinwheeling along until they hit a solid surface. But it's not like we can ACTUALLY do any of the things like turning or changing course in the air like there are in most games, and I congratulate you on getting it right.
There are a few things that I find a bit odd, but it's nothing major. In the scene were you are in the box riding down on a cart, I get wedged into the 3D shape, but I somehow managed to get off scot-free, after my computer recovered from the incident. I think it would be more appropriate if in some of the levels, if you get crushed by the 3D, you should be rather squished.
Other than that, I can't offer anything but praise for a job well-done.
