Also they can spin on their own in a handheld-
In a stationary device like a desktop trackball or an arcade cabinet, they settle but a handheld device is moving very slightly while being held and more vigorously when picked up/put down, which can move the ball. Trackpads won’t do that.
It’s why I’m putting off playing it again for a few years.
I’m over restarting the game again and again, konpeki plaza pls.
