MoreLess Bubble +1 bubble has similar property to the Bubble Mill in Bubble Witch 2 Saga, except adding only one move. When hit, or burst in any way, the player will gain one bubble in the shooter. If left unhit on a turn, it will switch into a MoreLess Bubble -1.
Avoid hitting the MoreLess bubble when it has a -1 on it. If it is directly hit or otherwise burst in any way, the player will lose a bubble from the shooter.
