It introduces a new game engine, the Game Boy Color, and allows players to create their own levels. It is the first game in the Super Nintendo series to feature a 3D effect. The protagonist is Keiba, a young boy who is taken to the city by his family. He falls into a coma after a car accident and is revived by a scientist named Dr. Fuji. Fuji reveals that he has been working on a powerful energy weapon that can kill anyone, but he needs Keiba to find and stop him. The game is set in three stages: the city, the laboratory, and the final showdown. Players must navigate through obstacles and enemies to reach the end, and they can only use the power of Keiba's energy sword to defeat the doctor. The graphics are colorful and vibrant, and the sound is realistic and calming. The game is a great way to relax after a long day, and it is also a great way to learn about energy weapons and their effects.
