'Greggs-Chan' (name tentative!) is a character design for our doujin game, Greggs Fighter. At the moment, we're thinking that she's going to be a secret character, or a computer-only opponent.
... We know we said that four would be the 'magic number' for characters in the demo version of Greggs Fighter (our 2D doujin fighting game), but no - the end is not yet in sight!
The third character for Greggs Fighter (Data West's in-development doujin fighter) is 'Jammy Heart' - a 'glass cannon' character, who fights by shaping jam into objects like weapons and projectiles.
