The whole Summertime Saga could be splitted in 2 main parts.
The 1st one, the good one that approximately was released almost 2 years ago and the 2nd-actual one, which is only a bland attempt of struggling in keeping the game alive, or mostly people hooked with the promise of releasing new content within a X date. There're lots of fanboys on this forum, most of them don't even accept a negative review or attack others, nothing wrong with that within certain limits and if you really like something, but the excuses I read over months-years are getting r-i-d-i-c-u-l-o-u-s. Patreon is indeed made for supporting an artist, but when the same guy takes advantage of it(as it's basically now his job), then you can't justify further. It'd be interesting to see the same situation with Kickstarter and eventually deadlines to respect.
Apart that why 3 stars? (scroll down for the newest rating)
For the reasons explained and as I enjoyed a lot having fun with Jenny, the sexy auntie and the puzzles-interactions with old characters in-game. They were funny, not soulless and mostly you had somewhat a story to follow, excluding the lame-coding, which after years it's at the level of a beginner or amateur(same with the Rick and Morty's game if you know that).
The negative part comes instead from the lack of interesting updates, an atrocious new plot and so many fillers regards stereotypes and politics that I was almost tempted to skip the whole dialogues for a while.
Remarkable it's instead the short Halloween release, mostly as I like the goth girl, but it can't fix 2 years of delays and low quality.
For the rest SS is a game that I'd in any case suggest to fans of genre and similar games,but that over years lost what made it interesting. Moreover I'm pretty sure the game won't be finished in other 3-4 years and still people will justify the dev, no matter what and in a neverending circle.
EDIT(update 0.20.8): I think the game will follow 2 directions now, that is random updates, or releases based on patreons' tastes, even more than before and introducing new(useless) characters. In any case the main story was pretty much rushed, after all these YEARS I was expecting a little more, even the Aqua's quest chain was more interesting than this. 5 months(7 if you exclude the small halloween update) for such a dull and common story is a joke.
The new scenes? Boring, not detailed, again a side view and you can't see a damn thing. The only one I'd save is the 2nd scene with Nadya on the sofa and that's it. If you don't understand my point try to compare them to 2-3 years old scenes(Roxxy,Eve,even Debbie's oldest ones). That's why I'll decrease my rating. At this point I don't even see a reason for being a patreon or just to follow this game further. The fanboys will keep defending him, they'll never admit the game has gone downhill, people with a bit of common sense will understand that he's pranking his own patreons.
