Well from all that I have seen its just random people making a thing as a hobby with no real experience or sense of responsibility. So as soon as they start raking in money most of them just crack and go on some wild as fuck tangents. Such tangents include: Going on a holiday with all the money and never updating it again, updating once every blue moon while the retards on patreon just keep pumping more dosh into it like its fucking Star Citizen, Scaling up production to such a degree the entire team just goes bust and the project keels over(or someone just takes all the money and makes a run for it).
A lot of things can and do happen, usually for the worse tbh. Of course there are people who actually do the "right thing" and imo this game isn't too bad compared to more mainstream stuff like Yandere Scamulator, Star Shitizen, Rack 2 - Making shitty 3Dmodels in Uniy is easier than drawing electric boogaloo and so on. From what I can tell this guy basically made a porn game with dogshit art got some cash in, scaled up got better artists and now has some decent fap material. Yeah the game runs like shit, but what do you expect from flash which is why he is now using unity afaik for the second act or whatever, these same problems is what Something Unlimited ran into which is why they are now switching engines too.
