Fighting games, in general, have a hard time getting accepted. For whatever reason, they just aren't much fun to watch to the vast majority of TASers. Even movies which allow the character to morph into other characters get rejected (see any reject Shang Tseung Mortal Kombat Movie). The opposite of this is any fighting movie with significant and interesting glitches. So, if in your test run, you find cool glitches, your movie will have a much better chance.
Anyway, my recommendation for this game is like any other that is weak in its publication chance - make a test run (doesn't have to even be the full game), upload it here,
