Anyone who's ever played games like New Super Mario Bros. or Super Mario 3D World knows that the Toad characters are excellent jumpers. But in Captain Toad: Treasure Tracker, they never leave the ground and now the producer Koichi Hayashida has explained why:
"We introduced a character with the ability to jump. But one thing we discovered right away was that if we played these levels with a character that could jump, we would have to make these stages very, very big, because jumping allows the character to go wherever they want. By taking away this element of mobility, the designers could focus on making levels much more compact."
He also says that legendary Mario creator Shigeru Miyamoto is a huge fan of the Rubik cube, and that's one of the reasons Captain Toad: Treasure Tracker exists:
"He's a fan of the Rubik cube. And at one point he was thinking about implementing a Rubik cube-style of gameplay into a video game. When Miyamoto saw what the team accomplished, he suggested they make Captain Toad into its own video game."
