Rain World is not your daddy's Metroid-style exploration game. It is a relentlessly difficult tour through a terrifying world of merciless, wild animals. As Slugcat, you need to act like a cunning beast yourself to even survive as you explore the expansive map. How do you make a video game that milks its thrills out of making you behave in savage rather than systematic ways? Creators James Therrien and Joar Jakkabson will joined us to discuss the making of their new title with Adult Swim Games, building an engine from scratch out of old accounting software, and how to make game characters that are equally grotesque and fascinating.
