Sorry for the very late reply.I love the capture based battle system in this game. I'm assuming it's a custom engine by the dev?
How difficult would it be to rip it from the game to use in a future game that I plan on making? Failing that what about rebuilding the system from scratch?
I don't know about extracting the system but I do know that the makers of the Deathblight RPG asked Ahriam for Asagi's system code and are using it for their own game.
