Yes, it's pretty hard. Maybe a little too hard seeing as most people are probably only going to give it one shot. The correct tactic (in this very limited scope) is to run straight home, but making sure you hit the shadows in front of you without going too much up or down (stick to either upper or lower part of the level. The path closer to the bottom of the screen is probably slightly easier, but I have succeeded both in the top, the middle (such as it is) and the bottom.

Essentially, you need to get as far as you can before the sun gets too high while simultaneously hitting the most amount of shadows. 
This build is very limited in scope and I am actually working on this game to flesh it out and see where it goes. I will be putting out a new build soon-ish.
