Defend your base, aim well and shoot, pop the enemies and get stronger. Watch out and shoot carefully because your balls are also your energy! How long can you survive? Each enemy has a different tactic, some are fast, some are unpredictable, some are just huuuuggeee. You only get their energy if you can make them explode. The higher the score the bigger the enemy! Choose your bonuses wisely and make the most out of your luck. Nuke them all, get lots of balls or shoot twice as much. Boom Ball Forever takes you to a imaginary universe where you protect your heart from enemies. Your energy is also your ammunition. If you can pop the enemy, you get their energy. More energy more ammunition more challenge.
