Mini-game sypnosis

My game will be about saving your crops from an evil drought monster. You are just a simple farmer working on the field. Then you go to bed and when you awake your crops are gone and harvest mites try to attack you. Then you go through various levels and then you find the monster that stole the crops. I thought this would be a great and fun idea for a game. This would also be a good learning topic for a game. When you fight the harvest mites they blurt out random facts about harvest and drought. When you defeat the harvest mites you gain experience and gold. After each level there will be a store you can stop at and look at the new equipment.
