I enjoy writing with you too. You seem like an intelligent and smpathetic person. :)
It appears to be the optimization part is one of the hardest things to do when you wanna “transfer“ (I forgot the word) a pc game to mobile, iOS or Android.
I watched some Blood and Lust on Youtube from the Youtuber UkeKooki. He's a fun dude. I first thaught he is Asian, but he said in his B&L video he can't speak Japanese, so he had to translate it with an engine (The game wasn't in English when he started it). His TA videos are alot of fun (I haven't watched much of his vids), because he is, kinda, shameless in a way.
(Are all Japanese Asians or are they considered to be Japanese? 🤔)
I know two more VN's you may never heard of: Oceans Blue and The Secrets. Although I think that Oceans Blue is rather a small game. Ahh and now I just remembered Guardians of ParVa'La. It isn't that long or finished at all, but it's pretty awsome so far, I suggest it. I gave it 5 stars (on my profile). It reminds me a little bit of WSSAP. There is also Let's Meet Adam or the Incubus Academy for you to check out (pc).
Technically we could follow each other so we don't miss out on our reviews. Although, I don't know if it works that way.
