Is it possible to do a "World Peace" run in a "Dark Side" run? What I mean is that: We do Dark Side but within the 250 moons we finish World Peace. Is it possible and can we submit for both categories with one run? We would make four videos so it is clear where the runs end but I am just curious if it is allowed.

You wouldn't need 4 videos, since timing would end when you both beat the game, and plus I don't think it's optimal to do world peace in dark side, also it would be allowed
