I didn’t think you were actually a real backer, but since you added the screenshot of backers only post on kickstarter, I’ll give you the benefit of the doubt.
A data point for you. Giant Spacekat’s last real employee, Amanda Warner, quit in May. You may have noticed that was the same month Wu last made any sort effort towards releasing the game. It is very likely that the game was mostly developed by Wu’s staff, and Wu herself simply doesn’t have the expertise to complete and release it now she’s on her own.
