Just to point out it is NOT an NSFW game. Very typical Chinese dev behavior of “looks NSFW, hint the player there may exist NSFW, but never has NSFW". Developing NSFW games will lead you to jail in no time without trial in the PRC if ppl report to the police. (Technically steam is banned in PRC, but VPN exist to hide virtual locations, however, you can't say the same with the dev's physical location )
Technically speaking, if you are "one-man dev team". if you hide your identity, And never wire the money you made back to China (just spend abroad or live abroad). maybe you can get around. That's the reason there are quite alot of Chinese NSFW artist exist on patreon. But for creating a game, usually you need a group of people and accountant who need to file taxes (Otherwise, you can pay for social welfare to your employees), It is nearly impossible to hide what you're doing. On the other hand, you usually can trust Taiwanese dev team. If they make a game that looks like it has NSFW content in it, they usually actually do.
