Cube Shooter: Hardcore

I think you might not even be able to reach 100 points, but here are the challenges:

100 - 150 - 300 - 500

-100 points: arrow speed reaches 2.00x and non-static cubes start to appear;

-150 points: the size of the cubes starts to decrease up to 1/2;

-300 points: arrow speed increases to 2.50x;

-500 points: maximum difficulty, arrow speed increases to 3.00x.
