Before starting, make sure to read the Tech and Glitches page.
This level is pretty simple: just spin-dash at the start to attain max speed, then continue rolling and jumping to preserve it. Do not skip Checkers, or you will end up in the hard/super hard mode prompt at the end. Jump into the flashing grabba before the midpoint to take the secret exit, cutting the level short and going directly to Bridge-Wheel Waterway.
Aside from rolling and jumping continuously, movement variations should make no difference in this stage: this includes big jumps, small jumps, long rolls, short rolls, which platforms you land on and whether you briefly flap over the bridge.
The fastest possible known time for this level is 15.966, although it's fairly easy to get 16.033 without any effort. Besides spin-dashing optimally at the start of the level and after the warp, it's not exactly known how to save the remaining frames. Since Checkers takes 0.500 seconds to pick up, the goal time for this level is 16.533; any 16.5 is good.
