I think as a game it tried to do too much and ended up worse than Sistina/Mai.
The exp obtained is worse than in the previous games, which means you actually probably don't get to level 50 by the time you reach the first final boss, and level 50 is when you get both your capstone skills and gear. At least you get some of the gear in chests in the last dungeon, but that still doesn't feel good.
It's also, well, very long in a way that feels bloated, and while having a a more traditional harem hero in a ntr game is a bold choice, I feel like I just preferred Mai and Sistina's characters much more than Sephira or whatever the harem protag's name is.
Given how long and insistent the whole "get money" ntr plot is, too, the weirdness of "just don't listen" was higher than in previous games, especially as the logic of why that would help with money is baffling and characters believe the guy is a great acountant.
