Hi,
Unfortunately, the nature of the project is such that it is probably impossible to distribute all the selectable backgrounds and characters (gfx+sfx) on floppy disks, so that it is not become a nightmare of changing disks. it is allmost 6mb uncompressed. That is at least 7 disks!
The HDD version has the flexibility to be expanded really easy. Everything is stored as an iff file. Anybody can duplicate and/or rename a character (or background) and redraw it with Deluxe Paint and voila it is playable!
But:
If someone wants to play from a floppy disk, you can copy the characters you want to play with to your "Character" folder on the floppy (and the same with the "Background"). You only need to change the "List.txt" to contain the names of the characters/backgrounds.
