Allright then. I guess I took your "MMX style game" in the title a bit to literally. Though I'd argue now that it sound more like a straight up fighting game.
And I'd have to agree with DeathBySpoon about price. Considering your offering a 2D product online, you probably can't get away with charging over $5.00 for it and the game will need to be high quality. I don't mean to suggest it won't be, just that it's going to take a lot to sell something vs. MUGEN, a 2D console fighter, or Smash Bros. Brawl once it's out.
