Your base is under attack by a barrage of missiles and enemy aircraft! It’s up to you, the base’s commander (who also happens to be really great at math) to keep the enemy from destroying your base!
For each question you answer correctly, you’ll destroy a missile, or a plane, but if you get the question wrong, you’ll lose a part of your base. If your base is completely destroyed, it’s game over! As you destroy enemy object, you collect, and that gold can be used to upgrade your base to help defend it.
If you notice any problems, please let us know.
