I was thinking what will be low level of effort for Dev to improve gamers experience without much refactoring existing grind labyrinth. As this product is great in any other aspects.
One of the options, put required stats levels in menu choices, like if some progression with choice is available, it shows required key metrics to advance with, like for example caress Melindas butt requires Relationship (RL)+150, or if relationship is irrelevant like Massaging Point (MP) 6+, or repetition required (RT) 3+ or combination of those and so on. This will greatly improve gamers experience, as player will get inputs on what stat he need to crank up to progress further, or if nothing in there it would tell that option is irrelevant at the moment and is just a stub for future update.
Just this small tweak, would cutoff great deal of negativity this game is suffering to be among top rated.
