The solution that the developers came up with for NEO is quite simple: make an entirely different game. That is something that isn’t possible on Switch, and as the re-release of the original on Switch showed, as good as the core game is, it does lose a little magic from the required re-work to a single screen. Like most, I wanted one, but the original game was so noteworthy because of the integral way that it used two screens on the Nintendo DS. Like most people, I wasn’t sure how a sequel to The World Ends With You would work.
