By god I wish. Sadly, no. There already is a thread about the beta, but I'm not going to bitch at you about it because I don't see a reason why, and it's not going to solve anything.
You should try sending Pixel an e-mail about it or something, and cross your fingers.
GOD DAMN IT DUDE, you modified your post. : /
Well, my theory would be that the story would be incredibly different from the Cave Story that we have now. Sue could have been some character that follows you around, Balrog (Originally named Puu..?) would be the main villain in the game, etc etc.
I can imagine that the beta would have these serene caverns containing large amounts of moving fog and tints of pure light. The small balrogs with wings would drift slowly across the atmospheres.... Idk
