Unless I'm very confused, there wasn't any kickstarter for Spacebase DF-9. Just the initial investment and then the early access sales. The first two weeks of the early access sales recouped the $400k investment from Indie Fund and others which makes more sense (it would have been very hard to defend them had they used kickstarter to raise money and give it back to investors).

There was a kickstarter for Massive Chalice but that's a different game.
