Whoever did the sound for the whip crack in this thing probably just slapped their desk with a ruler and called it a day. It's not layered at all, no initial snap, no trailing air displacement, just a single flat thwack. Really bothers me because in a proper bdsm setup, the whip sound is half the scene, you know? The wet smack against Iruka's thigh should have a different timbre than the one on Ayame's backside. Cloth versus bare skin, there's so much lost opportunity for texture. Instead, same generic hit sample every time.
The jingle when you fill the bruise meter is weirdly cheerful, like a phone notification. Totally kills the mood. And speaking of mood, who is this Indian guy? He's just... there. Dialogue box says he's getting too excited but the audio gives zero feedback for his state. Some heavy breathing loops, maybe a muffled groan when he's close, that's basic stuff. Missed that completely.
I keep going back to the whip though. You're clicking around the girls' legs, trying not to hit too hard, right? The visual feedback shows redness but the sound never changes intensity. Hit soft, hit hard, identical ker-smack every time. It makes the whole careful-clicking mechanic feel pointless. The cumshot sound is just a squirt, no variation, pretty much what you'd expect from something tagged hentaikey. No buildup, no rhythm to the impacts. Just a metronome of disappointed sound design. The Ayame character model is nice, I'll say that, but without proper audio feedback it's like operating a silent film.
