"Hijinks" makes me think of exactly the kind of casual mess-with-your-friends gameplay that can happen with Nintendo games. I like it.
As a side note, I'm curious to see how the game turns out. Nintendo Land was the only game I've played on the Wii U that made proper use of the game pad, and the ghost mansion was my favorite minigame.
I've had that issue with Deep Rock Galactic anytime I opened the Steam Overlay. No idea if it's related, but if you're using Steam you could disabling that.
