Quitting your job with only 4 month worth of savings, with a new mortgage, to enter an industry known for its oversaturation, extreme competition, and high luck element for indies ? That's insane. Maybe I'm just risk-adverse.
That said, I think he actually succeeded, despite appearances. Managing to release a working game in 3 month, that actually got sales, is a feat in itself. The game will keep trickling sales, if he's a developer he can probably find a job in a few weeks and enjoy the now-passive income so I'm not too worried about him. Keep cranking out games like this one and the income will pile up.
