Nice work! It's a great, creative puzzle concept that I think you could keep pursuing. For whatever reason, it didn't bother me that I couldn't anticipate the exact motion of the platforms until setting it in motion once, but I really wanted to know the mechanism of each block just by looking at them in the side-menu so that I could logically evaluate and order them. In puzzle 4, for example, there are two white "1" blocks in the side-menu that behave differently (one flipping back and forth to gray 1, the other flipping to gray 3 and counting down), so if I understand correctly, their initial number and color (other than solid white or solid gray) don't tell you the behavior. My gut was that a visual indicator of its pattern would put more focus on logic, and would require less trial-and-error gameplay. I realize that may just be a matter of taste in puzzles and others may disagree :). I hope that's useful feedback!
This is a creative concept that I liked -- really nice job!
