dude only so many paths can be worked on at once, and shit, it almost sounds like youre pissed hes not making the game the way u want, which makes absolutely no sense since ur not the one making it, itd be one thing if he was making a completely ridiculous and retarded game like my sister giorgia or something that has next to no real story, on 2 options at a time (continue "story" or game over), this is actually one of the better adult games out there, and it hasnt been filled up with ntr bullshit aswell.
devs have to prioritize certain things over others, and with an rpg rather then a vn u have to not only add story and scenes (which in vns are just simple backgrounds) but also dungeons and some times quests to go along with them which adds additional work to it, vns made in renpy (which is the proper engine for vns not that unity shit, its not meant for that dammit) is simpler since renpy does a lot of work for u when developing, think about how many years go into making a game like say witcher 3, that game took years to finish making and they even got lazy and rushed release since they only made a single new game plus playthrough before having to start a whole new game from scratch since they didnt want to bother adjusting equipment values for further lvls, tho they could have takin a page from blizzard int his regard, since diablos gear scales till ur at max lvl, the devs of witcher 3 didnt make a lvl cap which would have removed the need to adjust values after a certain point, point im making is u dont want things rushed cuz then the game just feels half assed
