In Oil Ocean Zone Act 2, the screen keeps getting dark and smoky as I play the level. As the smog gets thicker, the ring meter starts flickering rapidly, making me lose rings at a constant pace.

Losing rings from smog

Is there a way to clear the air so I stop losing rings?


There are chain switches throughout the level which will temporarily clear the air.

Based on the in-game timer, you will have about 30 seconds to find another chain switch before you start to lose rings again.

The smog cannot kill you directly, as the ring-draining effect will stop if the player hits 0 rings.

Interesting side note: The chain-pulling mechanic is a callback to Sandopolis Zone Act 2 from Sonic 3 & Knuckles, which had the same chains acting as temporary light-switches.

So, you know that smog that comes in? Well, it drains your rings, like if you have trouble breathing. The crew can't breathe the smog very well, so, instead of a timer, you have a drain mechanic that drains your rings, one per Second.
