This was (sort of) requested by ​⁠@demofinity!
This is a mashup of the Sonic Colours, Sonic Colours DS and the Sonic Colours Ultimate versions of Sweet Mountain Act 1. This version has an alternate intro.

Here are the links to the individual tracks used:

Colours DS: youtu.be/C-FpWXJISCM?si=B9yP_i3V41EaYlsw
Ultimate: youtu.be/tq4MbBb7fpE?si=HqtsMEevdtUuf0dc

The original art composition was made by Uekawa, but I made it a finished piece! Enjoy.
