Seafrog

A 2D skateboarding action metroid-like... without a skateboard. Play as a mechanic lost at sea with his digital cohort, Woodsbeard. Trapped at the bottom of a mysterious hole in the middle of the ocean, Seafrog and his AI companion, must go up against weird, silly, and grotesque enemies, not to mention some very big and angry monsters. If they hope to escape they'll need to build the fastest ship in the sea. Race and trick-combo through playground-like ships, breaking machines, firing off cannons, and salvaging parts that will help you escape the mysterious and alluring sinkhole that's pulling ships to their doom.
