Should be able to turn them off via settings on the switch not in game.Donkey Kong arrived today, it’s very good being able to play in portable mode.
However the rumbles from the joycons are annoying as hell, can’t seem to find an option to turn off :/
Purchased Donkey Kong via the digital store.
Then I realized that my micro SD only has 2 GB left on it......
Time to go and buy a new one it seems..
No demo. If you loved Rare's DKC games you'll love this.
At work. It's going to be a long day...
