Well this game was made back in... 2008? This is of Kan's first projects (and not the first remake of it either). He says he might continue it after FP and possibly remake it in the future for Steam.
Until then however, there's an open source team you can join if you know how to use RPG maker. Atm it's just mainly mapping. It's Kan's job to put in the main story, missions and events.
