Good update. Tho I think I have lost the ability to retrain perks when I paid Mira for tutoring. When I click the "questions" dialogue, it only shows WIP. Also, attunement is still bugged and won't show an increase.
That being said, the endgame adventuring content is still a bit too grindy. Granted, that will probably improve when all the girls get monsterfucking sprites so you can make a concerted effort to gain the essences and won't be essentially locked out when the first girl fails. There is also the problem that as of now, only one stat gained from running the tavern is relevant for adventuring, that being serving. Pleasure, attunement and refinement can only be increased through exp. gain which is locked behind studying, which is still spriteless with the exception of Alma. (You can also gain significant amount of experience through serving customers but two customers drain a girl's HP to almost nothing). The player is forced to sink a lot of exp into perks, then into stats that allow the girls to service customers for fame and then another considerable sum into skills that boost adventuring chance.
