I'm working on the music for this, too. Or I would be, if anyone had the faintest idea what music I should make ...
Well, there's the Title Screen, (optional: Character Select Screen), Intro Stage (not yet), Boss Select Screen, Stage Theme for each boss, Boss Theme, (optional: Weapon Get Theme), Boss Select Screen (after all eight bosses are defeated), Castle 1-x themes, Final Boss Themes, and Ending Theme
1, (a), 2, 3, 4, [5 6 7 8 9 10 11 12], 13, (b), 14, [15 16 17 18 19], 20, 21, 22
(a) is character select screen, [5 to 12] is stage themes, (b) is weapon get screen, [15 to 19] are castle themes, leading up to 24 songs, which is actually slightly less than a usual PSX X series game soundtrack. I think I am forgetting some themes, but still.
Hey! That's cool!
So you guys are developing a kind of sequel to MegaMari or is it very different?
It's like how Mega Man is to Mega Man X as to MegaMari is to MegaMari X.
The gameplay will be similiar, but the story? It's not something to worry about.
