Regards, John! I have also attempted to play as a guest. And everything about sweeping went well. Haha. I've played only 1 end thou. However, as soon as I started playing with my nick and hit several crucial shots, the sweeping became sporadic. And no matter how quickly or forcefully you sweep, you won't be able to get the desired line in the game where every sweep matters (you may need to sweep all the way). The sweeping in the game might have been made more sensitive and responsive if the developers had wanted to be more creative, but instead they made it "deaf" and "stuttering." You need to "repeat", You need to stop sweeping and restart it again to make the sweeping go out of "jamming mode," And doing that, time will be lost along with the shot and the game.
I appreciate you everyone agreeing with me!
