100% consists of all 120 Energy Spheres, and completing all challenge rooms (regardless of medals). Timing: Start - selecting Main Mode End - final hit on Magolor Timed to the frame: 2:50:30.887 Thanks to kirbymastah1991 and others for many strategies and ideas. The run is definitely improvable (and there's a death in 6-2 that costs about 1m17s), but not too many major things went wrong, and I think it's a pretty decent base run for showing strategies, comparing times, and things like that. Hope you enjoy it!
