the Musketeer scenario proves that Sora and Riku can be meddling with things at the same time, right?
If what we take from what the TWEWY characters is true:Sora and Riku are in the exact same place, at the same time, just on different plans.
"It appears this world is just like ours, seemingly split into two parts."
Sora's on one part, Riku on the other.
That kinda is the basis, however the Reapers are trying everything to stop the players, even setting traps to erase them all at the same time.Oh, I always figured that the basis of the game was win to survive. Then again, I never played TWEWY. Thanks
