well I LIKED IT.
partly because i wrote the music to it.
Thanks for the promo/ credits. much appreciated.
I think an improvement though, is the inclusion of sound effects when things happen (i.e. sword clashes, energy blasts, bullets, ect... you can find most of these on Flashkit.com)
The only other thing i'll mention is that it didn't seem to "evolve" as your title claimed. Sure, it had moving scenery, but it didn't grow more intense. Maybe go from like a simple fist fight to a weapons brawl, followed by a complete shootout.
Just a suggestion.
