This game is really difficult, but it did still make me smile! I'd slow down the basket just a little bit, at least on level 2 and 3. It took me a bit to understand the controls as well. I think binding the increase/decrease range to the scroll wheel might be an intuitive change to the key bindings, or at least add them in your bindings to have both the mouse wheel and 1 and 2.
Good job!
