I have the premium version on Steam. This game is 100% worth every penny.
RJ Rhodes has one of the best written Adult Visual Novels. This is the one that has sent me down the AVN rabbit hole, I have played many since, but none are as good.
This really is one of the all time best Adult Visual Novel games of all time. If you play the free version and wonder if its worth paying for, well considering the amount of content, writing, effort, and the voice talent, yes.
You are supporting the hard work of the developer, and I would rather she gets the money than a corporate entity that cares nothing for the finished product.
