I play that game too. In fact, one of my versions has a character made by some person. Vegito (from Dragon Ball Z!) and Super Vegito. I pretty much like playing with that character, ESPECIALLY because of his moves and combo attacks. Which WILL hurt a lot. And I reached Stage 120 in Survival Mode with him. But I used cheats, so yeah, it's obvious.
And I am talking about version 2.0a, since HEROFIGHTER.COM doesn't work in version 1.9c.
