instructions are in game. The secret level instructions are also in the game. At the secret level, you can also collect chaos emeralds when they appear, to activate the superform by pressing the S key, as long as you collect 7 rings in the game and all 7 emeralds without leaving any behind. The super form only lasts until the rings reach 0. You will win the level when you defeat all enemies. The "BOSS MUSIC" button is used to change the music of the boss fight from the secret level to other different versions, such as Sonic Generations, Sonic Mania and 8 Bits.
