I concur. It is one of very few porn games still in development where one can clearly see where it's going and how to operate within its world. One prison full of unruly men, one slap-happy female Warden and 5 levels to tame. I do not expect any game-changing events will be added on Lv 4 and 5, with or without additional sidejobs (apart from gloryhole and strip bar). She can try to be a valiant Amazon or she can finally get tired of it, give up and go down the slutty bunnyhole. Most probably, there will be several different endings depending on how Karryn conducted herself, but there will be an end to her wild adventure behind bars. There are way too many games out here that have been in constant development for years, with each ver 0.x to ver 0.x+1 update feeling like another episode of a soap opera that's been aired for more than a decade, or slow-burning season of Netflix comedy-drama series.
Having said that, there are many unexploited possibilities in the game so far and a few underdeveloped or ill-developed concepts. I hope the final pre-release version will have these ironed out, leaving the door wide open for DLC. And I mean proper additional content, not just a wardrobe with new clothes or hairstyles that bring nothing of substance to the table.
