Hi, my name is Derek Yu, and I'm a visual artist, game designer, and sometimes writer. In 2009, I started Mossmouth as a one-man studio to release Spelunky. My goal now is to collaborate with cool people and continue to make games that are dense and full of surprises, where players can express themselves against the backdrop of dangerous and exciting worlds.
