Good

I like the way you used the Bone Tool to make the stickman run, he did it really realistic.
Could have been nice with some sound like an explosion at the beginning though, but I imagine that it drags your attention once the music starts playing.
I also see that you went economic - Some people don't take into concern the viewer's internet cap, yet you did. Thank you
Since it's your first I'll give you an EIGHT, because it caught my eye.

Not that bad

That was kinda funny, but a lil'bit too short. Though as this was your first try I'm not gonna blame you for the length of your movie.

Hey!

Its quite good!

I thought no sound, stickman, crappy text = Bl@m

and then...

...it all developed- appropriate music, funny ideas; funny images; proper sound credit, and replay button.
Obviously some sound at the beginning and speach instead of text would make it much better, but you know that! I am surprised you didn't have an explosion sound, that is so simple- if you know how to add sound. Make the He into lower case, unless you think He is God.

Keep going, keep improving
