He's just running the numbers. In a best case scenario, he can pay rent and food with cashflow, but there's no money left over to pay for extra development cost. Art assets, music, and such cost money. Two updates a month is probably full-time work, so there isn't any time left over to build new apps, and no surplus capital either. Plus, that's assuming that each and every update spikes sales like the launch did. According to the OP, daily sales are currently holding steady at around 11 sales a day. That's a little bit over $200 a month in persistent revenue. At that rate, it would take almost a decade for the game to break even, given a cost of $20,000 to develop. Special note: This is for a game that cost only $20,000 to make. Building a solid AAA title can cost hundreds of thousands, or even millions of dollars.
