When I initially played through Captain Toad: Treasure Tracker on the Nintendo Wii U, I’d be lying if I said I didn’t feel that it’d be better suited to a portable console the whole way through. Nintendo has obviously realised this too, and in addition to wanting to sell more copies, they obviously believed that it’s a great fit for both the 3DS and the Nintendo Switch, and they were right.
I play the Switch in portable mode for most of the time, which better suits Captain Toad: Treasure Tracker. It’s really the only first-party Wii U game that Nintendo has ported to the Switch needs the touch screen. The game literally relied on you using the touch screen in the Wi U version to solve puzzles and stun enemies, and the same is necessary here (and works really well in portable mode), but obviously Nintendo had to come up with another solution to make the game work in docked mode.
