My game is keyboard input

My game is going to be using keybaord input. You are clicking on things on the game.  In our game you are going shopping and you click on things soyou can buy them. So our game goes like this. You are in a mall and you have to buy stuff. There are different items that you can click on to buy. After you get done shopping, you hav to figure out if you spent all of your money. I hope you like my game http://www.studyisland.com/
