Hello. I'll keep this brief, since my position comes from someone who isn't a patreon/boosty supporter, and is currently unaware of what state the game is on it's roadmap.
One thing I always dislike about Fem MC games like this is that scenes are completely tied to losing combat encounters, and I always hated that.
Two of my favourite H-games were Eroico and Wonderful Pink. The former an example of what I hate (despite absolutely loving the gameplay otherwise), and an example of my favorite implementation of Fem MC content.
In Wonderful Pink, most of the scenes were rather light-hearted capture and "interrogation" scenes by goons, but these encounters were still technically optional, and fit the Sentai/Magical girl genre the game was going for. The only sex scene occurs at the end of the game, with the player (or the closest approximation) sparing with Momoko, and eventually having sex.
Now, obviously a lot of people want to see the Fem MC getting fucked by monsters, it's the main audience for the genre, but I'll I'm asking is it would be nice if there were romantic scenes in the game with NPCs.
Now, here's a part where I'm probably gonna lose you/show my ignorance to the world this game takes place in, because I definitely would prefer at least one of these hypothetical "boyfriend" characters to be human. I assume this game takes place in some kind of spirit world, so perhaps it would have to be a human spirit guardian, or something, or maybe humans don't exist in this world? Again, I apologize for my ignorance, it's just kind of hard to find any information on this without reading the book, or so I think.
Thank you for you time, and good luck on your game!
