Play until you reach level 3 - The Scrapyard. After defeating the Cyclops boss made from rubbish the player will be directed down a slope towards a door they must destroy. Rather than destroy the door jump onto the wall above it then climb up, heading off-screen. Follow this route up and there will be a gentleman in a top hat who will ask the player if they want to fight in The Arena. Agree to this request then beat the three bosses that follow to access a quick, easy ending for this title.
