One lesson learned, if there are NSFW games with unique art style, better find out if the dev draw the art themselves or they just outsourced it, because Art is definitely the most expensive thing when it comes to developing this kind of games, if the dev outsourced it, they need a lot of money to keep the game alive, when the money decreases, the chances they keep the game will instantly decreases too, just look at Redlolly here.This is kind of a bummer as this had a unique visual style. This is also why I don't donate a dime until a game is complete. I've been burned too many times on games that are either unfinished or take years to complete. I'll donate $50-100 on a game as thanks after it's completed but I don't donate before.
One of the most successful example, Evakiss, she drew everything, so she already cut the cost of the development by very huge margins, she even did the writing and coding too, so the least she needed is the cost of living her life every month (Buying groceries, pay rent etc.) And she done it very well and survive until now.
So, the moment we find out the dev outsourced the unique art style like Redlolly did, we need to be sceptical
