Just played this for the 1st time at v0.20c and feel the need to write a review.
The game has 2 major upsides: the right kind of incest perversity (good writing) and is well tied together both technically and artistically.
It also has HUGE downsides. Art looks exactly like something made by a programmer with no artistic background but a ton of tenacity. It has a certain charm and is coherent across the whole game but in the end it's too simplistic and massively takes away from immersion. Another huge downside is the game being developed at a slow pace with little new content every ~month, resulting in story threads that take months or years to progress by just a few lines / images (this problem is amplified by game world being too broad for how much content is delivered regularly).
The game could be made wildly better by outsourcing all art to be reworked by someone who can draw at least at a Summertime Saga level. It's rare to have a game that could be made so much better through such a straight forward measure, even when you consider the cost and difficulty in finding the right artist(s). Another improvement would be to cut the game into distinct episodes with each having a distinct portion of the story and each episode being limited to 6-9 months of development. This would make the game approachable more often by paying patrons.
As things are, most people would find little value in being permanent patrons. It's developed too slowly to play every release and yet the game has become too broad to remember & resume from where you were if you want to play every 6-9 months, if that is even an option since I've seen you had to play v0.20c from start, which is an option most people would only have once every 1-2 years for a game of this size.
So, lots of potential, but unless the downsides are addressed head on the game has peaked and it's all downhill from here. I will definitely revisit it but definitely not earlier than next autumn. Also, A Town Uncovered wipes the floor with Summertime Saga when it comes to how incest is handled, showing just how easily DarkCookie bent over for Patreon like a good money whore.
