Rogue-like/rogue-lite games are sick. Frankly, they're one of the most entertaining ways to crank up the engagement and novelty value of content, and add a sense of achievement that isn't like ubisoft dog-water to game design/progression. Now, it's not *necessarily* the best for porn game design, but rogue-lite/rogue-like design elements can and do add value to porn games that focus heavily on gameplay, ala Karryn's Prison or Trapquest.
Problem is, doing it right requires doing one of the absolute hardest things in the world, designing a game that is good, and also isn't a formulaic copycat. The majority of porn games are twine/rpgmaker schlock with no real gameplay design work thrown in, with generally the better games either leaning into good writing and art, or detailed sim mechanics with stat spread sheets and tightly controlled progression, it's rare to see porn games actually innovate *or* put a heavy focus in the field of gameplay, but when they do it's based.
The *REAL* problem you have with this, and it's a legitimate complaint to have, is that the porn element of this is so small that unless you are enjoying this almost solely for the game experience it's going to be annoying. If it simply elaborated until it was so chock full of fleshed out porn content, then most people wouldn't care that it's a roguelike. But doing something like that requires a fuck-ton of illustration/animation work, obviously.
