I think this is pretty good and shows a lot of promise. I do like the setting, the main character, the general excuse as to why it's all so horny. I always prefer it when the developer actually puts effort into explaining the lore of their smut instead of throwing up their hands and saying "who cares, we are all her to just crank it anyways". 

The core idea of having a Mortal Kombat style gameplay where instead of fatalities you have short sex scenes where you defeat your opponents by making them cum is very interesting, and honestly makes a lot of sense. I mean, MK fatalities are now basically gore porn, so why not just make it a regular, less questionable porn instead?

Visually it's a mixed bag, but that's to be expected since this is a small game by what seems like just one dev, and it's not their only project in the making. The main protagonist looks rather nice I'd say, and so do the enemy female fighters. Men look kinda bland though, I wish more thought went into their design. Sex scenes are animated decently enough, but the fighting animations are incredibly jank-y. 
Also, female enemies moan during sex scenes, but male don't. What's up with that? Seems like a weird oversight.

I have a lot of problems with the game mechanically. I understand this isn't meant to be a super deep fighting game, but I still feel like a lot of things could be tweaked. 
The core idea is good: you need to perform regular attacks on enemies and when they're weakened you can perform a finisher.
Unfortunately, for some reason the finisher animation also plays even if the enemies aren't weakened, and it also doesn't kill them. And I just constantly ran into an issue where I accidentally performed a sex scene finisher on the wrong enemy. I think the finisher just shouldn't work until the enemy is in the weakened state. Make it just bounce off or something, idk.
It would also be nice if these sex scenes could be skipped, cause they are just way too long, especially since the game insists on playing the same voice clips every time they end.

Lastly, I made it far enough into the game to Futa enemies, but haven't been able to see one in action yet, because I am just getting killed over and over again at first screen. The enemies just get suddenly very hard: they suddenly have super armor with minimal visual indicators, they hit hard, the female enemies have whips that hit across the screen. And it's hard to take them down because there's several enemies, they all require a 20 hit combo, but once I start focusing on one, the other one smacks me and interrupts my combo. 
I don't know how to get past this screen, and this just isn't the good kind of difficulty in my opinion. I really hope this will get tweaked, cause I am interested to see where this game goes next.
