Honestly, I don't feel like I got the hang of this game.
I do understand what I need to do. I just can't move my mouse fast and accurate enough to keep all the balls centered in the normal way.
So, instead, I cheesed and got 225 points 🧀😏
Turns out all you need to do is just hope that the balls clump up together on their own, then quickly shake your mouse vertically in place. No need to move your mouse around since all the balls are in the same place!
