Ultimately it's up to you whether or not you want to make the level easier. For my part, once I got the timing down, it wasn't that bad. I will say that the most difficult jump is from the third set of floating cubes to the fourth--the cubes just don't come close enough. The jump from the fourth set to the last one, however, is easy.
The hardest part for me was the third section--the one with the floating cubes. It took me quite a while to get the timing right, jumping from one to the next.
