Have they stated why they need the money ? It looks like they are trying to "gauge interest", or that's, at least, the reason I suspect. It's a convenient reason to try to make money out of a shitty Unity demo and then not be tied to the actual finished product for having benefits.
Probably to hire freelancers to make what they couldn't find on the Asset Store. Games are expensive to make and 45k isn't that much when you have to pay people.
