Nice
Noticed you don't stream your sounds. Methinks you should be in the habit of doing that. I like it a lot people when people do that.
Also perhaps try to get a wider array of sounds. I noted that you really repeated a lot of them. More sounds=fresher atmosphere.
Nice use of panning (sounds wise). Not enough people use that.
Cute graphics ^_^
Haha, cowboy fights are certainly like that. Missmissmissmissmissmissmiss, HITHITHIT! :P
Why is it called Crazy Horse? I expected the main character to be a Indian. Or at least a horse (like in the title sequence)
Haha, funny that he alters his wanted poster, then puts on a disguise exactly like the one he drew. Defeats the purpose :P
So yeah, nice and great. I liked the Pangea one better, but this is still really good. Keep up the good work.
P.S. Flash MX 2004 sucks, I use an older version myself (I have both)
