Actually, I would probably have continued, but it was my first game, I made a lot of mistakes, didn't get enough support on Patreon, spent almost a year on it, so I decided to hone my skills and try another project.
You were earning like 700 dollars a month even 1 month delayed in your game. Honestly I actually enjoyed your game as BBC/interracial NTR is more hated than ordinary NTR game so it is expected lower income. Just imitate Life after victory by obliviousNTR, where he presented 3 paths. BBC, goblin and hobo, even that game has no goblin and hobo yet. People hate when they see another human race portrayed as superior. But what obliviousNTR did is make the black guy in the category of "lower being" in equal to goblin and hobo. Of course if you can, don't put QOS related tattoo unless you want to make pure QOS/bbc game.
Also do not put big dicks only tattoo on the girl, you don't want the people playing feel bad. Less people playing feel bad is enough, like small dick and can't impregnate that is enough.
RENPY is good for shorter term of the game development, RPGM is good for longer term.
The problem with RENPY is you have to constantly produce images which is easier than RPGM at the beginning stage of development only, but the problem with that is long term. RPGM has lower images produced, and images produced are only important scenes.
