Actually the most pressing thing is to make transitions work within the stages - not the animating of them so much as getting other sections of stages on there and getting a good switch between them. I've come this far in making a game before but that's new to me. Everything I've done is just one stage demos, mostly in AMOS.
Re. Final Fight, there is a lot of work left to be done, but the greatest part of that is graphics + sonics. I'm going to post later as to how some of that is being done.
