MasterGame

MasterGame is one of Serponge's most well known levels. In fact, it is a complete video game with a story and everything, made inside the GD level editor! Which proves how talented Serponge is. You are a cube captain, your ship crashes, and you wake up in a penguin world! Then you have to complete quests and find your way back to your ship and fight the boss! This "game" also has a hard mode.
