1.0 is out and story mode is a thing now, so that would be a very good run to put here. Also it has gems in it, so a 100% category would work well too.
As of now, the rules do not say anything about when the timer should start and when it should end for a MSQ run. This should definitely be added so run times can be consistently and accurately measured. I recommend the timer start being when the initial "Loading..." message disappears, as this is completely dependent on the runner's internet speed and is unfair to include in their time. I would also recommend the end time being when the player reaches the clear screen rather than just when they beat the final level of the challenge, as there is still some menu-ing to do after entering the warp.
