What is Mossmouth? Mossmouth is me, Derek Yu, and it's my video game company. I'm trying to make interesting, cool, and challenging games. Why Mossmouth? Because it sounds strange, and I like strange. And because for me, moss represents the growth, texture, and little details I'd like to put into my work. Stay mossy!

Current projects: Mossmouth is currently working on Spelunky for Xbox Live Arcade.
