Act 1 & 2 are quite the mazes, especially with Act 2's big slope 'n slide section, but just remember where you need to go to make these Acts more of a breeze than they already were since you don't have to gather Flickies.
Unlike in Volcano Valley, you can't really control the speed of the Act 3 boss. Just hit Eggman as soon as you can when he descends to the moving ground of the conveyor belt.
