Thus, you’ll need to invest some real cash in the game to buy blue crystals which will allow you to purchase weapon and defender bonuses earlier than you would earn in later levels.

What this did for my gaming experience was changed my need for using bonuses (i.e. sky rain of tennis balls, freeze-a-player snow, etc.) to a strategy dependency.

Remember, using bonuses cost crystals, which are a minimum of 3 per use, plus you may earn only 1-2 crystals in a given level. Crystals are harder to earn, therefore, if you do not folk over cash to buy more in the Google Play Store you’re screwed.
