Educational Game: Adding Game

I used Gamemaker 8.1 Lite to create an adding game for kindergarten students. The game includes addition sentences with sums from 1 to 9. It's a very simple game since it was the first game I created. The player has to count up the objects and use the keyboard to type the sum. Also because it's the first game I created, it isn't anything Earth-shattering or as fun as it could be. This game is more of a foundation to build on for a future game to me. It was interesting but also very time-consuming to develop a game. I would like to attempt to make another, more in-depth and fun, game in the future. Here is a link to download my adding game.
