Other than the bug fixes (which I haven't really found any other than the laggy saving and such) I think there is barely anything you could add, the game seems complete. You just need some innovative additions to it, like say, an option to start a level with x lines partially filled with blocks to add to the challenge instead of starting off with a clean slate.
