You unlock "HARD" difficulty setting after beating the game once.
Just beat every level on the unlocked "HARD" difficulty. HARD mode typically adds enemies, removes springs, and redoes puzzles. Its really not that bad.

For this achievement you need to clear all of Sonics act missions on hard difficulty. In order to play on hard difficulty you need to go to mission select, and when you choose a mission you can pick what difficulty, normal or hard.
