Is this game a scam, like Waifu Academy or Summertime Saga? Because the game's pretty good, and I sure hope author is meeting his set deadlines.
I don't think he has set deadlines, but I would say it's no scam. It might, if something goes wrong, never see completion, but a monthly Patreon is getting their money's worth so far, with episodes being released. A scam attempt wouldn't have this much content in it before getting abandoned.
