You're just a little ninja dude running around. And jumping over lava. And going underground. And jumping over lava. All in a days work. Until you realize: wait, this isn't normal! I'm just a regular dad! In a ninja costume! At a Halloween party gone wrong! Don't touch the red tiles;that's the lava. NO WALL JUMPING! Arrow keys or WASD to move! 9 levels! So go run your buttocks off!
