GREAT!!
Dude, I've seen quite a few sprite animations and I can tell you this one got a GREAT quality. I was actually upset when it ended. This was perfect, really. You got the spirit of what an animation of that sort is all about.
The only "suggestion" I can give you at this point: MAKE MORE. Elaborate some sort of history-line. Longer animation. More characters. Keep it up!
I eagerly await some more :)
