haloooo! thanks for your interest in the game. i wish that were possible, but i think that option is no longer applicable for adult games. :(
promote? are you by any chance stupid? most of, if not ALL of the games on here are created by a single person. so you just want to pay for a complete product, when more often than not, it's one person developing the entire game themselves, which needs to be supported in some type of way monetarily, in order to complete such work. what a genius, dude.
