Still can be improved. Optimization requires the jump at the end of the null space section and the rentals system.
I have dialogue on just so I can time the jump around when Sonic says "power." It saves about .5-1.0 second depending on how precise you are.
The first skip requires that you boost for just a split-second before using a homing attack on the spring. Obviously, you miss the spring and snag the railing which is what you want.
Now... the next skip has actually been made obsolete by myself. I will post that new sub 1-minute time soon as well.
