Why not, right?
As long as people keep "shoveling money at them," there's less incentive to work hard for their money. If people wait for the VN to be finished and THEN pay them for their work, I believe the developer will produce a better product. As it stands, there are so many things going on in the story, too many characters introduced at once, not enough character development for the ones already in the game, and slow development of the VN itself, I don't really see anything happening in this VN at all.
So many VNs get put on hold and some even get abandoned because the dev put too much on their plate at once, which is exactly the direction I see with this dev. Only time will tell if Radiant will become something special or if it will become just another statistic of failed VNs.
