This game has the potential to be pretty cool! I love the twist on Tetris where you reject the shape you were given and manipulate it into something more useful; if only the real Tetris allowed you to do that. However, for this concept, you really needed operations more advanced than rotate and change direction. It sounds like you were working on a way to split the object into multiple parts, which would have made the game much more interesting.
It's also too bad there is only one level. As it was, 95% of gameplay was figuring out controls, and after that you solve it in 30 seconds.
