Thanks for taking the risk and testing the waters. I'm glad it paid off for you. Congratulations on a successful game! Of course, though, it is a hybrid, not a pure visual novel, but that's what gamers expect anyway.
I can't even contemplate making another game like Fatal Hearts at this point, not just because of how long it took to make but also because I'd need another Big Plot Idea that ticked all of my buttons while not reusing anything (much) from the last plot... it's going to take a while to recharge.
Yeah, I have to make sure that each game I make and even each project I work on is different in theme and style and execution from the other, if not radically so. Gamemakers naturally and automatically develop their own 'flavors', so its crucial that they still come up with a diverse 'cuisine' for the players.
If I had a team of artists and musicians and the retail connections I would get to it, so the fact that I can do things solo is also a curse as well as a blessing. (1. If I can do it myself, I'd do it myself 2. I regret the burden of having to do it myself 3. Repeat from step one.)
Anyway, I'm aiming for at least DL-site-level commercial quality (even though some games here look far better than the worst offerings there). Aiming for at least a midlevel not-so-amateur-looking work. Then, take advantage of the freedom of being non-commercial by releasing something totally uncensored.
Non-ero works in general are recommended for the Western audience. Since Japan is peculiar that most of its PC games are ero. (Japan's main market is console games. In the West most PC games are violent).
