Is invincibility the only change you made? That doesn't seem like it would be worthy of its own game.

"I don't want to record myself playing the whole game just to get a rejected game" I really have to question your dedication to playing the game, running it, setting up the boards, and moderating if you don't even want to do one run. If you really care about the game than do a run caring about the game to get your first time, and then submit the game to the site with that run.
