I understand the whole issue with payment stuff, but why not try and find a way to work around it? I feel like there could be a way to buy a "sfw" version of the game, kinda like how Hunt & Snare is, and just have a patch file that you can get from somewhere to reenable the nsfw part.
Like Archipelagates is an anthro hack and slash at its core, but if you get a patch/dlc it gives you the nsfw parts too as a "free" dlc/mod.
