Close, but no cigar.
This is a competent reimagining of the Darkest Dungeon I with a lewd theme. Where it counts, this game follows its inspiration with a certain degree of diligence—and some elements it openly cribs, like the stagecoat's bark for the Paladin. Anyway, there's a solid array of classes, gear, perks, and other elements that enable a true sandbox experience: you are allowed to explore and experiment with the systems provided, and develop your own favorite style, or an overpowered combo. In some ways, like with some negative quirks, the game even surpasses its mainstream counterparts: you can strategize to make some negative quirks into a benefit.
Such complexity also comes with some unfavorable builds that hinder a new player really hard, but that's not uncommon for strategy games in general. The start is often the most difficult part, but that's a design problem so common that I can't and I don't hold it against porn roguelite devs. Still, if I could give one advice regarding the gameplay to the dev, it's that the game should put its thumb on the scale for lowest difficulty dungeons, limiting aqcuisition rate of hard-to-uncurse gear and cursed classes that are more dependent upon rare gear to be effective, gear that you can't have early on.
But for all its competency in gameplay, Ero Dungeons just doesn't take the prize. Why? Well, leaving aside the undisputably, um, unispired art and animations... This is a game with a lewd theme, but this is not really a lewd game.
There's very few truly lewd curios, and curios don't generate any lewd content for the player, be it images, or just text vignettes. Same for most lust-inducing attacks; most of them lack animations or flashing images to show the player. So even if you do find a build that is powered by high lust, it's not going to stand out visually, and worse it's not going to stand out narratively.
Some games do manage to combine narrative storytelling—limited, perhaps—and procedural content. Ero Dungeons as it stands is not one of those games, because your pawns do not give a good impression of having a personality. Which I find to be a big downside, when the goal is to make good porn. Again, coupled with unispired art, there's no other way to describe it but lacking.
Still, as an adult game with some gameplay of reasonable depth, it's a rare beast, and deserves some measure of praise. Four stars for v1.11.
