This is rather disappointing. This was my favorite prospective nsfw game so far, but I suppose I will have to scratch it off if it will never receive another update.
I must however question the logic, if this game couldn't support itself enough through nothing but itch and patreon income, how will the next? Especially given that now everyone who knows you through this game knows that if you can't miraculously pull enough funding to self-sustain, the game will hit EOL far before completion?
If nothing else, you simply should not have such a high expectation of a project like this. Community-funded, niche, nsfw, itch and patreon-only projects practically *never* make enough money in isolation. $15 wasn't a high asking price when updates were frequent, but for a project this early access that's now abandoned, it's ridiculous.
