Level 12 is good for 1 star only

Starting Bubbles: 47

With careful aiming it is possible to get 1 star almost every time you play level 12, but IMHO it takes at least 2 Magic Potions to get 3 stars. The golden Spider Potion and the potion that gives you 7 extra bubbles in the beginning of the game. When you have played level 11 for the first time, you sadly probably haven’t any potions. But the 3 stars is good to save for later on to be collected with a little magic potion help. :)
