I'm also interested to know about this reward because so far I played both games for more than a day and no reward was given to either of the games. I think you were supposed to get this girl on Hentai Clicker (Felicia) and maybe HH version of her on the other game? Either way I'm also hoping I didn't click something wrong and lost my chances in the process. I'm using Nutaku as my main platform by the way.
