Sonic Colours: Ultimate - 100% Speedrun - 2:09:48 [RTA] World Record!
I started learning the 100% category a couple of months ago and I managed to improve the former world record by quite some margin!
With that being said, there is still lots of time in this run, but a sub 2:10h definetly feels good.
