I have found an inconsistency/bug in block party.
When I punch while holding a leap or teleport in my hand, they get used. It is quite annoying, as I can’t hold these items while trying to collect powerups. Also, it only happens some games. I might experience this for an hour, but later on in the day, it won’t be there.
Note that I play on switch.
