I am planning to make a video featuring all my platinum level runs in Dr. Robotnik's Ring Racers. It's gonna take a good while to finish. Not only are a good portion of these platinum requirements difficult, but there is also about 150+ levels in this game (to my knowledge). So, until then, I will occasionally drop videos similar to this one where I will show all the progress I made in the form of platinum level runs.
