As 54mf said, it needs more polishing. Kickstarter is a great idea. You'll surely find scores of hardcore gamers interested in funding a game that suits their tastes. As long as you satisfy the elite gamers, casual gamers (like me) will follow suit, just like we did with Super Meat Boy.

What I haven't addressed, 54mf has done already, so all that's left is a "good luck".
