Well to be honest there at least seems to be quite a bit done with the rework here from my understanding. Compared to some other games on here that for instance has been doing a tech update for about 4 years now I believe and still has another 1-2 years left before thats even done but I honestly have no idea how big of a change a 5-6 year long tech update will do for the game. But most of the games on here especially the big + high quality one's don't have any kind of incentive to actually finish the game since most of their income comes from patreons paying them to work on the project so as long as the project is a work in progress they get paid. So some of the games have been in development for over 5 years with no end in sight, though my guess is at least some of them will be finished in a few years since in for instance one of them the dev has mentioned that the game size is making it so that the engine the game is running on only allows for about 2 years more of content. If they will then transfer the game to another engine or just end the game there I have no idea.
On this game however I have to say that for especially some of the scenes there is a need for a rework since for instance when having sex with the mom, if I remember right, the MC's penis will look like it's entering her through her stomach when I believe she does the cowgirl position. Outside of that I really liked the premise of this reverse world since there really aren't a lot of games like that from my knowledge. Together with the fact that most games including futas with a male protag either have them do NTR vs the MC, turns the MC into a sissy for futa domination or the games that include MC's dominating futas / just having male x futa are mostly text based games or at least the to me good one's are. So this felt a bit like a fresh air to have futas + nymphos everywhere who all want guys, even though their all sissy guys pretty much. Feel free to recommend me good games where there is some futas in.
