Well its too bad that so many people applied, now I'll barely have a chance to sneak in. Still, I wouldn't just let $600 go away without a fight, so here's some of my samples.
Important stuff: I can code in AS2/AS3 depending on your preference - either works for me. I've been coding for probably 6-7 years in some flavor of ActionScript.
http://media.putfile.com/Space-ShooterRT S A space shooter/RTS combo game. My most recent work. Click to go to build screen, space to shoot. For some reason on Putfile they make you do a right click - play thing to get it to start up. Obviously not finished, but still cool :D
http://media.putfile.com/Zelda-again-81 A Zelda styled game. (Also not finished, I just like to show it off)
http://www.newgrounds.com/portal/view/29 9271 - A mousegame with a few tricks. (Finished this time)
( http://www.newgrounds.com/portal/view/39 7088 A little game I made during summer when I figured out that people run out of momentum when they try to code big game ideas. )
