Have you considered Early Access on Steam? Maybe with the note that the game won't be completed unless it does super well or something? Even with like a $3 price tag or something?
I'd love to, but I honestly fear that the gap in the amount of cash we need is too severe for that approach.
While I'm SUUUPER tempted to put the game onto Steam for the addition of leaderboards alone (and don't promise that I never will), I'm also a bit afraid of attracting negative reviews for an unfinished product to both our developer and publisher accounts, where other games are selling full retail.
