Fantasy Zone is a short, colorful arcade port which somewhat uniquely is a shooter that does not autoscroll! Since there are no levels to scroll through, the boss battles start when eight of the enemy bases have been destroyed.
In this run, The8bitbeast saved 00:09.35 seconds over the previous movie by using different weapons and optimizing the shopping portions of the game. The submission notes explain the improvements in greater detail.
You can watch the complete run being played back on a console.
