Very well done.
I am highly impressed if this is your first animation. I liked the scenes where you had the cursor drag the stick figure around, it was cool to see the view change perspective. The animation was good in about all of the parts, and yo chose a good song to use as well. This is a good way to get your name out on the site as an up and coming animator, I liked this.
The only problem I had is that some of the scenes, preferably the stick killing ones, got highly repetitve. Stick flashes are a dime a dozen on this site, but I thought some, not all, of yours showed some creativity. Aside from that, Iw as entertained from beginning to end with this flash. I'll be on the lookout for other work from you, keep it up!
