I give a 10, but...
Would it be possible to extend it?
The sound is amazing! But I agree with the user below. It's far too short, and gives you the impression that it's going to be even better, however it just ends.
I can imagine some orchestral string instruments coming in for a real dramatic feel.
If you could extend it somehow, then I, and many other Newgrounders I'm sure, will appreciate it.
