He is a very money-driven dev that is for sure, aside for the desperate DRM implementation he also utilizes every opportunity to try and garner more patrons with constant stupid giveaway competitions for everyone who shares/wishlists/likes the game on a variety of platforms. He truly thinks this game can make him a millionaire or something lol.
But he apparently dosen't realize that NTR is a niche fetish, and even more so is the NTS subgenre of it. Even if this was the best NTS game in the world, he would still never get the thousands of patrons you see on other games. Even if his DRM was perfect and he managed to make it so every player is forced to pay, it would likely not garner him any substantial amount of supporters.
What is funny to me is that he knows most of his current patrons found this game on pirating sites like this(according to a poll he made). Despite knowing this he desperately try to shut his game down from those sites when it is pirating sites that gave him most of his patrons and the money with it. He is essentially trying to abuse the pirating sites by trying his best to lock the game from pirates while still trying to attract patrons from them. Really scummy move tbh. If I had some coding knowledge and 15$ to spare every month, he is the one dev I would gladly crack and share all his shit on day 1.
