I think it would be a good idea of giving us the option to not have the blessing to avoid bad endings. It's lackluster of losing to one of the bosses or characters with lots more interactions to suddenly appear at the church again instead of being kept as a husband.
I once had the idea to mod in a new area that you can take a quest for, with the big thing about it being that the blessing won't save you while being there, making it a risky rescue mission for fallen colleagues that are kept there. I already collected some pictures from other monster girl games and galleries, wrote some dialogues and stuff for existing ones, thought of some factions in that area, but I am simply too lazy to look into the modding/implementing part of it all so it never really got beyond that point. It would definitely make things much more interesting to have actual odds due to a deactivated blessing, especially for interactions with feared monsters like the hellhounds, but the domination part of this game has always been rather soft, in both directions, so I doubt we will ever see it officially.
Will this game eventually have h scenes during battle? Or will it just be text-based scenes with only the enemy's sprite?
This is on the to do list, one or two have already been implemented as far as I know (the blue slime at the very least), and the imps already have an art teaser on the patreon. Unlikely that it will happen for all of the girls at the current progress speed, or several for the same monster, but definitely an improvement.
Honestly I'd already be happy if most monster girls weren't fully clothed during battle, and had at least the option to take stuff off after a while. Beris is a good example for how to handle that well. Even if art is there for the monster it sometimes does not get implemented like one would expect, Cerys new nude art is neither appearing in battle nor in the losing scene, not even in the interactions with her in her room despite the text specifically mentioning that she is taking her clothes off during it, it only appears in the seduction event of the labyrinth, which seems like a massive waste. Things are kinda the same for the manticore, in some of my favorite scenes with her sprite stays dressed for some reason.
