BL means Boys Love.
Morenatsu (misspelled previously, my bad) is actually available for android now. It's called Morenatsu Revisited (not on itch anymore; https://www.furaffinity.net/view/27724434/ ) and I recommend it. The one on itch started out the same but now the fans are putting more depth into the characters, which I'm excited about.
Yeah, I've played a LOT of VNs. They're my bread and butter. Gay, straight, trans. Doesn't matter to me, I'll give any VN a try.
Basically I just mean scenes that don't change no matter what your previous choices were. For instance, the group outings with friends in Tennis Ace. The only dialogue changes are determined by choosing Library or Tea House. Or the Prefecturals, the dialogue is all the same.
And no, I'm American. Anntoinette, however, is a family name so I mixed it with my pen name. I quite like it. ^^
