Neat.
That was cool, though a bit short. You're a good animator, and everything was relatively smooth. The floors and stuff didn't look that great, but that's okay. Also, you used great sound effects and great music. You might want to put in a play button. Also, the back button didn't work.
The golden crystal didn't really seem to have much play in the animation, other than that some guys were protecting it or something.
Anyway, keep up the good work!
