Well, that's the "beauty" of kickstarter. She doesn't. Morally - yes, sure, absolutely. Legally - none at all. ;-) But - to her credit - I do not think this was a scam. Many inexperienced (semi) amateur developers just don't realize how taxing the development of a game can become, especially when the initial excitement is gone and it turns into just "hard and boring work every day". Particularly in case of the (very ambitiously) branching product, which grows into "exponential hell" with each and every player's decision made. Imho she knows now for sure she will never finish this but is ashamed to openly admit it to her audience, especially if that audience actually paid her money. And if I'm wrong - I'll be only glad to admit my mistake.
