May have dipped with the cash, but it's not like that amount of cash is going to take them far in life. If they want to be a scrub and quit, that's fine. The game is decent, but not good enough for anyone to feel bent out of shape over. Dev showed their true colors, quit with nothing to show for the time spent, and we can all move onto supporting good devs.
