Level 14's awful. It is not, however, impossible. What it is, though, is the absolute worst level in the game. Get past that and you have a clear shot at winning this thing. (Although there's still some hard levels in there)
As for level 9, all you gotta do is fit those Tetris shapes into a square, at which point they all vanish and you can collect the cores.
What this game really needs is a quality setting option. Always allow the player such an option.
Also it's a bit strange that there are three mouse cursors -- your normal cursor, the in-game cursor, and also the green ball and each one lags behind the other.
