The only thing that the update adds is new skincolors:
The most common gold collectible, the Ring skincolor is based on your health.
Usually used for speedrunning, the Speed Shoes boost their way into the skincolor field. [Based on Sonic's sneakers, NOT the box.]
That's right, another animated one, the godmode color is here. Not to be confused with Hyper lmoa.
It's a trap! The Eggman has created this skincolor to oppose the other three in a much more evil way...
