Just like every other patreon based games. Rule of thumb is try to avoid any games that doesn't have that completed tag unless the devs has a good track record or it was consistently good.
Any games that try to steer away from the main plot / characters and instead keep adding worthless content about side characters that was suggested by their biggest backer is a huge red flag.
At that point the game has 0 passion and the person who made it only did it for money and will continue milking it as long as they can, until they hit a block and do some bullshit tactics such as "remaking the game" or "completed but stripped of all it's promised features." It happens all the time with WEG and patreon backed games.
you should check out Twisted world, it had futa and stuff in it, but it has almost every thing you said to be warry of but its a great game, good secens lots of side charcters and stuff, the only prob is they only update every 6 months, but ITS A LOT OF CONTENT.
i just think its the devs, some devs dont have ideas and or want to put in work, so they drip feed cuz they stuck/want to milk ppl, but snatz from twisted world hads a cool story i never seen before good characters dev(tho there are a TON of side characters lol, mostly from contracted high patron request, but they have sex scens)
and he is "remaking" the game, but not really he is switching engines or what ever cuz the game is getting too big and he is updateing the look of the girls/guys.
look into it, it may not be fore you but
