Pretty good for a short nukige. It actually doesn't waste time. You know why you're playing this; the game knows why you're playing it; there's no need for anything more, and the game happily gives you what you want without unneeded filler.
Art is great in the H-Scenes, though the H-scenes lack in variety. There's one scene with anal, one scene with P-play, one masturbation scene, and the rest is bdsm. Combined with the fact that there's a lack of location variety, it kind of makes each scene after the third feel the same. Especially since the background during the scenes aren't too detailed.
Edit: Forgot to mention, MTL is decent. Beside some sentence structure issues that aren't too egregious and pronoun issues, the MTL conveys everything really well.
Haven't completely finished it, but from what I've seen, its a good 4/5 or 8/10 for what its trying to be.
