Funny you say that, I just found a way. You kind of have to pull a Super Mario Bros. (World 1-2) and walk on top of the ceiling at the very top of the stage. A comment on Zone 0 explains how.
At first, because of this I thought the Past of Act 2 was unbeatable. I took that as a challenge, of course, and searched and searched for a way to beat it. The method I developed was taking the tip top route at the very beginning of the zone, and instead of dropping into that corridor with the multiple layers and the big bomb that follows you, I would dash off the ledge, and sail through the air, off the top of the screen, and run over the whole corridor. Move to the right, jump One more gap, and voila, Sonic can avoid having to take the chutes or hit that spring altogether.
