The big issue this dev keeps making with respect to the storyline is that they feel it's important that a character can't be missing from the game for too long before they need to make an appearance. So every update feels like this laundry list of speaking to x/y/z to get their one line in and by the time we get to some kind of story progression the update is over because so much time was spent "making the rounds" on all the other girls.
The number of women is on the ridiculous side but it actually wouldn't be a problem if the dev from the beginning went with the formula:
meet new girl > setup plot point to help/woo girl > resolve plot > relegate girl to backlog/collection > move onto next girl
This gives the freedom to have a meaningful interaction with each new person but then when that's done, move on and have them make cameo appearances for big harem orgies or if it makes sense to have them appear within another girl's plot for some reason. Just don't waste time having 30 women show their face just to effectively say "hi, I'm still here" or get stuck on making new sex scenes for girls we've already had many for unless you intend something significant to come out of it i.e. pregnancy.
Don't throw too many new women at once too. The introduction of that color coded group of girls during an already overburdened scene of new girls, it just gets boring.
Other devs who only have 5 or 6 women total can get away with dedicating every update to cover everyone in some way but when you have 50+ it's just not feasible without harming the narrative.
Also there is a fine line you have to walk along to avoid a harem turning "cringe" and for me that line was crossed when they had all the girls in bikini's lined up in a row and bent over just for the MC to enjoy. It takes a lot for me to feel embarrassed? in a virtual scene in a game...but that's how I felt when that happened.
