The principle of Bubble Struggle is simple: try to burst all the bubbles. That sounds simple, but isn't always that easy: that's exactly the reason why the Bubble Struggle game is so challenging. You can collect all kinds of bonuses in this fun game. Sticks of dynamite for example, that reduce the bubbles to the maximum. You can also collect extra life, and ice crystals that freeze all the bubbles in the game. There are two different shields, too, that protect you temporarily. The icons with a little boot inside accelerate things temporarily, and the green icons with an M inside slow down the bubbles. The red arrow is worth extra time. Then, you can also use special weapons: double harpoons, ice sticks, flowers and medals. These medals burst all the bubbles at once. Make sure that you're not hit by the bubbles yourself!
