The audio isn't just bad but absolutely earbleedingly horrible. The main menu music is actually the one I used for testing- I wanted something nice to listen to while I tested- and I was going to swap it out before deciding it would be better to leave it in, but only five seconds of it followed by the worst sounds imaginable.
The controls are actually shuffled every time the game is played. It starts with a fairly normal layout- A/S/D for punch, Z/X/C for kick, arrows for move- and then shuffles them all around.
I never thought of randomizing the character and stage select buttons. That would have been a nice touch. Next time, perhaps.
Some of the text is always in Russian. It's meant to evoke some of those really lousy half-translated shovelware games. Of course if you're actually on a Russian system that effect falls flat.
