Magic Defense is a tower defense game that has you defending against evil gummies! Build gun, cannon, acid, and electric towers that will attack the gummies. Once built, a tower's range, rate of fire, and damage can be upgraded. You also have two abilities (meteorite and swamp), which don't cost any gold, but must recharge between each use. You start each level with 20 lives, and lose life if an enemy exits the map. Depending on how many lives you lose, you will earn up to three stars for completing a level. You can use these stars to upgrade your towers and special abilities.
