As in, it isn't giving more arousal? Or it isn't letting her orgasm when it hits max? Or she's orgasming, but the number just isn't going up?
Yeah it’s intentional. Had some trouble balancing the late game since I have no idea how to make a proper clicker, don’t play many of them. Wanted the nail have some impact so it resets all the pins. The nail is implemented as a pin so it resets too. I could have fixed it and tried to make the game a normal clicker, but thought that spamming the nail to make her cum nonstop was a fun little twist.
