Production Pipeline of a One-Developer Studio With 50M+ Downloads

I run x2line, a lean studio with 50M+ downloads across iPhone, iPad, Mac, Android (including TV form factors), and the web. I’m the only full-time developer. I manage production, ship updates, and coordinate long-term art and animation contractors instead of an in-house team. I’ll cover: how to scope version 1 vs later updates, how to get usable assets from contractors, and how to choose the next feature or fix so the game stays alive for years.
