A lot of people say you are missing things in the plot, but i disagree.
I think its excellent that through your rather open story, you allow us to interpret it how we want to, to look inside ourselves.
If theres anything to be improved on, it might be slightly better background graphics. Oh, and the transition from the stickfigure shivering on the ground to the morning wasn't done too well in my opinion.
The choice of music couldn't have been better. Overall an excellent piece.
