I know how it feels
That has happend to me so many times I can't count to it.
You start on something awesome, and don't save for awile and then flash crashes and you go all nuts on flash. My, my.
The flash:
It was really nice, I love your intro thing too. The shout: SUN! just sounds amazing to me XD so anime-ish and such.
Anyways, the flash was quite fine. I loved the idea of it, very much entertainment =) Too bad it was so short tho, I wanted to see him go even more nuts, like.. You know throwing stuff all around and bashing the screen and such stuff.
Constrictive Critism:
The character could been abit better, like you could add more detail, better hair, highlights and such. Though the character didn't fit really into his animation, but I guess that was ment to be though.
You should also have done the animation like his sketchy one, like awesome fbf and stuff like that.
Either that this movie were really nice, I sure enjoyed it.
Keep up the good work.
PS: How long did this take YOU to make? I'm just curious.
