In ICZ1, Sonic starts off by sliding down a mountain, and traverses through an icicle cave with Tails, when Sonic and Tails exit the cave, they fight a boss and it turns daytime. In ICZ2, Sonic and Tails traverse through loops, in and out of the second portion of the cave, and then they fight Dr. Eggman. When Eggman is defeated, Sonic and Tails free the animals from the capsule and head to Launch Base Zone. ICZ1 = Ice Cap Zone Act 1 ICZ2 = Ice Cap Zone Act 2
SEGA The melody you hear in this project isn't used officially, I composed it entirely, the official song was based on Hard Times by The Jetzons, made by Brad Buxer. The prototype version was made by SEGA and goes by Gmaj to Fmaj, and it loops forever, and my version goes by Gmaj.
