$1000?
You get props for the character/stage selection, but really, how could you possibly need $1000 for the production of this game? Granted, servers for the online mode... But really! Most people (Who use Flash) could probably make this relatively free.
And yes, I know how to program/script and use Flash, how hard it is, etc. I'm just saying, if the producers of this are wanting to be paid that much, it seriously is not worth it.
NOW, for the positives of this Flash.
The customizable controls and the selection of everything, like I said, are nice. They always gave me problems. The 3D-ish menu is pretty cool, as well. What you should DEFINATELY do is make it so you have combos for your attacks, and you can't just hold down the attack button. It basically kills the purpose.
