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.
