Not sure what he did, but one thing he didn't do was sulking in disdain.
Creating a working game this day is easy, or at least a lot easier than 20 years ago. But getting attention is hard. You need attention AND a good game to get anyone's time or money. So tell me why I should sit down and play your game for more than 10 minutes right now. You have a vision, you have a plan? Great, communicate it to me, I am listening. You have crafted something playable with love and sweat after years of educating yourself. We all know that not even 10% of people wanting to be a dev make it to that point. But is your game good enough? The first thing I noticed is that you have taken a track from Secret of Mana as is, just changing the instruments. This may be placeholder, good, but going into funding like this might turn off anyone that notices it too because it drains some credibility.
So "What did this person do to warrant $170,000 in donations?": He convinced people. Are you convincing yet?
I have no idea if he deserves the money or not. Regardless, the world can only be as just as the people on it, so expect injustice. But the people in this thread were all honest with good advice as far is I have read.
