I assume there is no actual sex and it's just some nudity for the adult content. So then, we look at the gameplay. It would be pretty good for a porn game, but since this isn't one, it needs to reach a higher standard.
This is a Darkest Dungeon clone. More specifically, it's an Iratus: Lord of the Dead clone. It copies most of the stats and combat mechanics from that game, which also takes inspiration from DD. The problem? Skills are bland and you can't look at enemies' skills to plan out your turns. Most classes are interchangeable with not much distinction. I found no manipulation and forced movement skills that affect enemies' formation. You don't even know what skills they can use from their position. Your heroes' skills basically boils down to strong damage, dmg + status (stun/bleed/disease), weaker AOE, some heal/curing, and limit break skill that is universally a medium power AOE damage for every single character. It has an intimidation (sanity) dmg stat, but no class specializes in this form of attack. This makes it kind of pointless, since sanity synergies need dedicated teams to make it work. It took me one expedition and I was already bored. Game tells you that you need to do 10 expeditions (3 battles each) to reach the next story segment. That's 30 fucking battles, and each battle is quite hard and time consuming on normal.
I'm sure most people who are into this genre started with Darkest Dungeon. If you are itching for more, I suggest Iratus: Lord of the Dead and give this one a pass.
That said, I found the lip syncing in the intro cut scene to be pretty good. Their expressions and dead eyes + awful voice acting kind of makes it funny though. Still, it was a good effort that might have payed off if the combat was refined a bit and had more creativity in skills/classes design.
