Here is my feedback regarding the MC: From what I saw in the first version, the MC had a Tanned/Brown skin, then you changed it to White, and now to Black. You mentioned making the change because it’s popular in porn, well, i don't watch porn, so I don't know what is or isn't popular, However, the audience for Hentai Games, NSFW Games or Porn Games, whatever you want to call them, is completely different from the audience that watches porn. People who watch porn usually don't care about the story and skip straight to the scene, people who play hentai games are the complete opposite, not only do they pay attention to the plot, but they also immerse themselves in the story as if they were the protagonist. So, my point is that what’s popular in porn isn't necessarily popular in games, and I’m speaking generally about pornographic content. Regarding the MC's skin tone: You said you switched to black because it's popular, but most games with a black protagonist aren't popular, I don't know why. if you do a quick search, you'll see that games featuring a black MC aren't particularly popular, honestly, I’ve never seen one that’s popular, and the games I have seen are high quality, like I said, I don’t know why they aren’t popular, i don't know the reason for this, but if you search for It, you'll see I'm not lying or making it up. That said, my recommendation is to include an option at the start of the game where players can choose their skin tone whether tanned/brown, white, or black, that’s a win-win for everyone.
Good luck with the game 👍
