My wife and I have been trying this game out, and we would occasionally see the whole board fall asleep. If we woke it up with a button press on a brush, we’d end up changing the brush’s color and accidentally made a move that created a new brush for a player.
I’m unsure if there’s a good solution for this, one suggestion that comes to mind though is adjusting the game to only paint neighbors with a button press to help keep the blinks awake?
