Well animated, but too long and slow.
First, too many play buttons. I hit play... then I hit play again. Then I start watching the cartoon. But it's not the cartoon, it's just your little logo intro thing, which is too long for a logo intro thing, seriously. I get it, you're proud of your kung fu kick there, and it IS well animated, but showing it twice, and the whole lead in thing - meh. Too much.
Then I REALLY start watching your movie, which is well done. I assume the voices come from the game? I've never played it.
My biggest complaint is that it's very long, and slow in places. Some of the fighting scenes - particularly where he ducks back to dodge a sword blow - are not convincing, that scene was a bit awkward and it took me a moment to understand what was happening. But again, the main thing is that I felt like you could have edited a couple of minutes out of it and it would have really helped the pacing a lot.... however, seeing that you spent 8 months on it, I can understand why you'd be unwilling to remove any of your hard work.
Maybe I'd enjoy it more if I played the game? I dunno. I'm giving it a 3/5, because it didn't suck, but was too long and not that interesting. And I'll similarly give it a 6/10 for the same reason.
