Pretty nifty
Pretty nice. Some of the graphics were a little clunky, but overall they were pretty good. The style is great, I like the sort of futuristic feel mixed with the whole demons thing. You might want to work on the opening story just a bit. The sound I give a 5, the music was good but you need some voice actors if you really want to pull off a good score for sound. Violence, 5. There's fighting, but not a lot of gore. Thats not a negative, though. No interactivity, no humor, but its not that type of flash. Overall, good job. 7, you could step up some of the movement to make it smoother and more human, study how people move and apply it. Then get some voice actors and you're good to go.
Make some more, that's my last suggestion. You'll only get better if you keep making them.
