You can destroy nearly everything in the game

This was hinted at in the first reveal trailer for Donkey Kong Bananza, but yeah, you really can basically demolish every level in this game. See a large mountain? You can punch a tunnel through it. Want to go down and explore below your feet? Punch your way down and do just that. You can even break off chunks of the world and use that to destroy stuff. Nintendo says that all this destruction is possible thanks to the more powerful hardware of Switch 2
