Rex Rocket is a 2D Metroidvania with 8-bit graphics and a wry sense of humor. Set entirely on a spaceship infested with shapeshifting green goo, the game features more than 110 rooms, branching paths, and multiple power-ups. It's currently available on Steam for PC, with Mac, mobile, and Ouya versions coming soon. In this week's IndieSider, I explore the first few levels while chatting with Castle Pixel artist Robert Maher.
