The developers of The Legend of Zelda: Tears of the Kingdom introduced a new ability called Ascend, which allows players to pass through ceilings and reach previously inaccessible areas.
The Ascend ability was originally a debug feature used by the developers to quickly exit the game's caves, but they decided to implement it as a gameplay feature.
The implementation of cheat-code-style abilities like Ascend created challenges for Nintendo, as they had to ensure that data-loading issues didn't result in empty locations.
