Silly question, but why not just continue the project under Duel of Shadows? As a side note, I actually like that name better :)
thanks for your interest :)
Duel Of Shadows was kind of a working title during the game jam because I've focused on a "boss rush" game. I've broaded the concept and want to have a bit of a world in which everything takes place. This would help with design of levels, picking music and creating story beats.
And probably not all bosses and characters will look like the current "Shadows".
So think of the duels of shadows taking place in the Ashlands. :)
