Just a warning
If your going to make a serious animation. The graphics need to be brilliant. Comedies can top the weekly charts with visuals that are barely above par because they are incredibly funny.
But they wont be looking at comedy your turn round, only your storyline... and your animation. So you best have an amazing twist or amazing graphics locked up somewhere.
The idea, looks good. It looks decent, and if nursed well and thought out to its full potential then you could deliver something very nice. On the other hand, if not enough thought goes into it... it may just end out shit.
This preview was nice, it wasnt just a couple of seconds long and barely telling us about what the flash will be about. It was informative, and almost exciting. The only problem, if you havent heard already by EVERYONE, is the fact it has no sound.
Anyway, best of luck with the release of the real thing.
