If you're willing to believe that even after fours years of development, with the entire original team quitting, and the last demo having come out two years ago, that this guy is somehow still making a game, do I have some vaporware to sell to you. Remember that this game is built in Unity and is supposed to be a "Fully animated Dating Sim/Visual Novel". The most labor-intensive aspect of this project is obviously going to be the programming and animation. We have no proof any of that is being handled. Without that, we don't have a game.
Another thing to keep in mind:
Unlike Patreon, which is literally just "throw money at this guy," Kickstarter does threatens legal actions in their terms of use against anyone who fails to deliver, on the behalf of the pledgers. Whether or not they ever make good on their word, I wouldn't know. However, I wouldn't put it past someone to fake updates to keep their ass out of legal trouble.
