In a nutshell: Give everything you have and more to their kickstarter project!
We need to reach those stretch goals. There is no better option at this point. Maybe if they'd start counting the purchases on their website towards the stretch goals, it would be worth it, but even then -- the kickstarter number is psychologically imporant. It's a real shame that paypal payments aren't factored in.
PayPal is factored into stretch goals and even in new dungeon thing.
