There used to be a small game that I think was in this series, I cant 100% say that it was created by this developer but it was definitely heavily inspired. It was a Christmas theme spinoff with the same characters, where you just sorted images based on if they were Christmas themed or not (disregarding lewdness), and there was a part at the end where you controlled a characters vibrator. Is this something that this developer made, or do any of their games include a vibrator section like that? I haven't been able to find it around the internet anywhere.
