The Chapter entitled The Top Of The Spiral is considered by many one of the most surprising final sections (prior to the final boss battle) in the entire series. In this mission, players must avoid the onslaughts of variously themed traps which reflect the regions the players have already fought before. The traps are very hard to dodge and appear rapidly, from fire-breathing dispenser blocks to simple poison-thorned spike balls. The closer the Stoneship is to its destination, the faster it will increase in elevation until it reaches the end of the climb. The entire background of The Spiral changes into exotic yet simplistic rainbow colors as the ascension commences.
