The core fetish behind the game has always been cursed loot, rather than porn in general. Of course, due to the lack of H-games - especially non-RPGMaker, non-VN ones - the audience is a lot broader than that niche. So that's why is there so much equipment, so many debuffs and so much complexity. I've recently started adding more in-combat grapples due to popular demand, but it never was the original focus and isn't my strength as a developer.
I'll be honest, with the current game I can't see the appeal at all. There's another game which the name is Kinky Dungeon that, in my opinion, has a better execution. Ero Dungeon main flaw for me is the unnecessary complexity that does more harm than good. It does not need this complexity. The quantity of status effect is so absurd that I constantly need to check the manual just to see what does what. It would be healthier to the game to unify those into major status effects similar to darkest dungeon, and some as status - like protection -, again, like darkest dungeon.
At last, yet quite important is the porn. Is no coincidence that in-combat grapples are popular demand, that's what people are expecting from your game. I believe the current formula is not ideal and does not delivery at least what the name suggests. On top of that, the difficult is too extreme to enjoy the content.
Your game has great potential, it definitely has a solid base, the problem and analogy I make is: Your game is a car, it has that ferrari engine, now it needs some wheels, suspension and so forth. Polish the combat then tune-down the difficult if necessary, focus on content like grapples and see how it goes.
I know that is not an easy task, but is what I can do as a player xd, hope it helps
