You're absolutely welcome, I've never considered you a troll I understood your point, and as I told you I was only disagreeing on your opinion about the tag issue in itself.
To me ( i repeat personal opinion) the content of fendom was enough, since it wasn't the central idea of the game, the entirety of it is based on the gradual corruption and bending of the will of the MC in order to make him become a "new feminine person" (caption necessary since I found the term sissy slight offensive due to being used too much in an offensive way all over the internet, so I grow somewhat disturbed by it's use even when done carefully and attentively as in this game, again personal opinion I don't want to offend anyone with this personal stance) willing to undergo any act of a sexual nature, as a sub and happy to do so.
And I'm absolutely sure the dev will reach to you, he's very considerate, kind and always attentive to everyone opinions.
Agreed on the last part of your post, the maledom is certainly prominent, that's true and will certainly need the tag.
