Amazing!
The sound was great. Animations were cute, yet well-drawn, but I consider these as simple details compared to the plot.
I really liked you using symbolism. I probably failed to get all of the symbols, so I saw only the most basic ones, like the faceless parents, the balloon that took the boy away from the grass, and more like that. Maybe I am putting more meaning to your flash then there really is, but I doubt it.
This is real art. Art that makes think what is a happy end. It is touching, yet provocative. It bringsup new ideas.
I actually have some advice but, I will spare you the details. I don't want to ruin the perfect score that there is here on this page.
Keep up the good work!
