i have to second it a lot of the mini games feel just like filler to slow you down and the Muscle Mary one is plain unpleasant enoguh to not mak me want to pursue the quest (doing that mini game 5 times!!! no way) -i get if thats what you want as a developer but there should be a scaleable effect
actually it wasnt really just 5 times, if u failed the follow up quiz u have to redo it again. Muscle Mary initiation event in the plan inst just one simple side quest, cos it will open up muscle church events once yamaneko becomes a church sister, so i dont wanna make it plain boring side event, so i intentionally to set up obstcle there.
i think some of stat grinding are there to keep players away from doing event after event after event, if i ever want that, i would just go straight unlock everything from begining, or have event lined up one after another, then i dont need to give npc all sort of dialogue, not put effert into mapping, no need to do all combat sequences etc. i think that's how developer of Rina: elementalist of manahold felt, he's tired of just pumping out event one after another.
i dont wanna make mindless porn game, i wanna make a fun game with adult elements in it, but of course, if some of mini games are notoriously toxic then i will readjust them.
