Its a short game, and disappointing after the first . Not nearly as good . Don't buy it It has the maniacal sex of the first but it does get tedious and repetitious. The voice actors are great, the graphics , exactly like the first. Not much Minimal animation. Not as engaging as the first game.

The Mamiya family returns once again, this time with a kinky femboy in tow. It’s easily the most disturbing entry in the series yet, involving "spunk noodles," "steak enemas," and an overwhelming fixation on poop that may be too much for some players. The story is paper-thin as well. Unlike the first game, there’s no major twist or surprising revelation. So negative points in that regard.

SLEEPLESS Nocturne isn’t as good as the first game, SLEEPLESS -A Midsummer Night’s Dream-. Nocturne is shorter, derivative, and not as enjoyable as the first game. There’s only three in-game days (less if you hit a bad end), and a lot of the backgrounds and sprites are reused from the first game. The sex scenes have a familiar pattern and don't introduce anything you haven’t seen before. While there are five endings, it doesn’t take long to see them all (not too many branching choices). It took me seven hours to unlock the gallery, but most of the endings were pretty short and not as good as the first game. I would only recommend Nocturne to fans of Sei Shoujo’s art and can’t get enough, or those who like to be cuckolded and enjoy more scat and watersports action.

If you’re into darker adult visual novels with a strong focus on character design, SLEEPLESS: Nocturne delivers pretty well on what it promises. It wasn’t entirely my type, but I can still say it’s a solid experience for the audience it’s aimed at. The atmosphere is one of its stronger points—the mansion setting in particular stood out and gave me some unexpected Nocturnal Illusions vibes, even down to small details like the dog. Overall, it knows its niche and leans into it. If that’s your lane, it’s definitely worth checking out. 4 out of 5 star
