I saw one review that said the game is grindy. I think this is entirely false.
As an early Fire Emblem-like game, this is incredibly satisfying with simple tactical gameplay and a squad that levels as you play. There are a lot of maps to play on, and I never really needed to play any of them twice in order to progress. Some fights are inevitably more difficult than others, but I can count on 1 hand the number of times I needed to really reload the map or maybe play another one a second time to level my guys to make it easier.
I'm actually surprised at the amount of sexy content that is here, as each map has multiple sexy scenarios. Of course the 2 big downsides to this is that much of this content is locked behind losing, so you'll no doubt save scum if you want to see it but not waste 20 minutes replaying a map. Also the other downside for me is how hot the women are, yet we never get to see any real sex, though it's entirely understandable given the vibe that they went for.
As a NSFW game, I 100% recommend, one of the best I've played as the core game is actually fun, and the art and writing are on point. I actively wanted to play more and finish, and it took me about 10 hours. Disclaimer, I haven't beaten the final extra boss, because she is definitely hard. Need a bit more grinding for that one, but she's a special case and clearly they wanted to challenge you.
