Fantasia is a game set in the dream world of Mickey Mouse, where Mickey must find missing musical notes scattered across four imaginary worlds: Water World, Earth World, Air World, and Fire World.
The worlds are filled with magical creatures such as marching brooms, skipping mushrooms, jumping cacti, flying horses, dancing hippos, and many more. The music in the worlds is straight from the movie, including pieces by Bach, Mussorgsky, Beethoven, Tchaikovsky, Stravinsky, Dukas, and Ponchielli.
Fantasia gameplay involves collecting special items to keep Mickey 's strength up and earn bonus points. Spell books, stars, crystal balls, potions, and dinosaur eggs help him along the way. Enemies are dispatched by bouncing on them or casting small or large spells. Bonus areas with wooden doors contain additional magical items.
At the end of each level, Mickey takes the notes he's found back to the conductor, who sends him back into the world to keep searching if he hasn't found enough of them or gained enough points.
Fantasia was released for the Sega Genesis in 1991.
