Sonic Tag Team mod - WIP 5 (We "Megamix" now)

Welp, took longer than expected, mostly because PC died, then I lost the progress I made in my WIP 4 vid, so I had to redo it from scratch again and... well, tried to add some stuff. Mostly bugfix but as well as some cosmetic changes here, particularly Knux's unique UI, item boxes and starpost. (based on Sonic Megamix for characters to have their own stuff) PS : I'm currently looking for someone being able to make a custom "act clear" jingle for Knuckles (altho, Sonic Mania-styled), if interested, drop a comment ! (credits will be given, obviously)
