Enjoying the hack so far. Curious, though if you could put a guide out there concerning recruitment and side quest requirements. I made it to chapter 14 on one of the paths, and was surprised how long several of my characters seem stuck at level 20 unable to promote. It makes me feel as if I've missed several side quests, but I'm not quite sure.
Glad you enjoy the hack! Astra's planning on writing a guide when we get further in making the hack, though we didn't put very many promotion items into the current release for difficulty control reasons, so it's perfectly normal. Our next planned patch should have a lot more promotion items. The sidequests we have so far are 6x(automatic on Musain/A route)/8Ax(kill boss in 8A) and 11Bx(kill boss in 11B). Did you get those? There are 1 promotion item each in 8Ax and 11Bx iirc.
