If he does, he should stick to three LIs split path. Seven LIs split path is unworkable. That means drop Dina. She did not raise interest and only served as a rallying cry that the dev forced you to choose between ugly monogamous LI or attractive girls who sleep around.
I generally don't think paths are a good idea. Individual scene paths are one thing, but "routes" are usually not a good idea for an update based game.
Every route splits a big part of the content, so an update where a developer made 40% scenes for all, 20% per love interest for a total of 100% of the update content, any player following a single route will only see 60% of the work the dev did.
For a 7 LI split, this would be something like barely more than 50%.
This generally will make updates seem a lot smaller to the player than they actually are. The result of this content-splitting is that updates seem small, progress little and doesn't seem worth playing - discouraging patreons to resubscribe and instead having them wait a couple months for more content to be worth immersing themselves in the game again.
Update based indie development has to be done very carefully when it comes to routes, in my opinion. Games that aren't updated but fully released and sold are different, because they don't feature this trickle content. But they're generally not support by patreon-models but follow the traditional publisher/investment financing.
That's usually one of the great things about harem games. They don't have paths, they just have choices of what content you want to see (what LIs to have) and how that content should unfold (kink/fetish), allowing players to go back & try a different path without having to skip through the entire game from the start.
Might have to do with lacking patrons too. Should have stuck it out. What did he expect for v0.1. Even the best release AVN this year, Tides of Succession, has a scant 15 patrons for v0.1.
My guess? Since they seem to be intend to overhaul the game from the start, there won't be an update for quite some time, and that means it would be quite a while before the rerelease and even longer before the first update follows. So any patreon would have to be very patient and wouldn't see any reward for their support anytime soon.
