If the 800 days are work days this means 4 years of work. ~200000 dollars really is not much for this time frame - you could even call it a bargain :) Anyway, I think I won't donate since I feel like I might lose the money when the goal is not reached (I don't really want a discount on the license fee).
Well yeah, if the person doesn't deliver, you've helped fund them, but get nothing back. That's why kickstarter projects aren't supposed to supply actual value for the pledge. A lot of the latest one offer the product as a bonus, but don't tell you that you won't get the product if they fail.
