Here come a pack of answeres, I missed a notification so I just read the 4-5 new pages since my last visit.
About DRM: There is a files encryption (so this may explain why failed modifying damages) and thats all, no tracking over players to know their IP and ban them from Patreon. But as it have been mentioned, there are matching attemp to know the Pareon names of people posting updates.
About graphics: some may have missed it, the had to change some characters design because of Patreon. It was changing or leaving Patreon.
About updates content: I'm following the game since the beginning (may have missed few month), updates always add few content, OP is November 2017 and the game is v0.4. If v1 mean full game so it's not even half finished. So claerly it does not worth playing each update.
About other Boner games: what I read is Boner have abandoned/on hold all his previous games, you can find them by searching Boner Games on games (filter with title only).
About incest patch: The author had troubles with Boner bcause the patch was the full game with modifications and not only the modified files. Then with DRM it means decrypting game -> replacing files -> reencrypting game, lot of work for a game that was only on v0.3.
NB: Those who whant only sex scenes you have an ingame cheat system that allow you to unlock everything.
