Vanessa Saint-Pierre Delacroix And Her Nightmare is a puzzler utilizing rotation as a solution mechanism. Also, it's got a cool cubic thing going. Babel is a similar concept with retro graphics. This time you rotate the levels in a 2D/3D spacial adjustment, also very cool. The Creature is a platformer with some rotational puzzles thrown in for good measure. Despite it's rudimentary appearance, it's built on Unreal UDK tech.
