Just played through the majority of the game for the first time. Honestly, besides adding a potential marriage option and maybe a real true ending where you select one girl or several to be with, I'd say the game is pretty much completed. Instead of revamping all the content, I feel like the dev is way better off just making a new game entirely. Either that or making a sequel or spin-off but I'm not sure how well that would go.
After finishing the game I went to patreon and here to see the general perception the game has from the community, and it seems he's being accused a lot of milking patrons, and stalling on updates. All this could be avoided if he just said "Alright, I'm making a new game and it's going to take a long time for anything playable to come out". Atleast that way we could look forward to some actually new content instead of a widerscreen and handfull of scenes for girls no one cares about.
