I play on joiplay and it says I have the DLC/paid version installed, but there wasn't any NSFW options. There also wasn't any option to customize the MC's pronouns just the name but even then when I put in a name, the characters still calls me "Angel."

Unfortunately, my games aren't supported by third-party apps like JoiPlay, so I can't offer any help or fixes T_T
14DWY and its DLC are being developed for PC users (Windows, Linux, and Mac), as specified in their descriptions. I also have no experience with using or developing for JoiPlay, so I'd be unable to assist with any bugs or issues you encounter. I'm very sorry!
