Kickstarters for games tend to work extremely well.
(from well-known people, that is)
Take MSPA's Homestuck, for example. The goal for the homestuck game was 700,000$ and within two weeks it netted 1.5 million.
I don't know the approximate size of the MSPA fan base when compared to Nifflas', but I'm certain there are a lot of people who would throw in a few bucks here and there for a new niff game
