I found a pretty cool route that allows you to skip the elevator tree thing on level 1 by going through the roof. It only works with Tails tho. I managed to perform it perfectly on the run and it saved like 15 seconds.

The rest was fine, except at the very end where I almost choked in the dumbest way possible. Still, I think I didn't lose time as it seems Eggman spawned even when I was below the bridge.
