Pretty simple but with a nice message. I enjoyed the overall aspects of this submission and it's fairly delightful. I think the two characters could use a little more detail if you are going to make the backgrounds simple; you know a little more shading although you can leave their legs arms simple if you wish. It seems some of the characters' faces near their mouths aren't filled in the last scene but that's minor. I think if you are going to do a flash as sweet as this, it would be best if you use fonts that are less blocky than the one you used; something more curved or make each letter custom. I really liked the choice of music; it was simple and lovely. Overall it was pretty good. Nice work!
The whole concept with the message makes it a great story and the music makes it even beter.
