Worlds of Billy 2 is a simple 2D platformer, with strong inspiration from Lode Runner. A young boy, Billy, has a problem with his imagination. In his dreams he is in magic worlds, that he has to travel across and fight against imaginary enemies. For this Billy has to dig holes, wait for enemies, and when creature falls into the hole, Billy can bury it. When Billy defeats all enemies he can go to a teleport. The young hero can't jump, only climb on ladder. Ten different worlds are waiting for the player, for example a pirate island and a spaceship.
