my game ideas

In my game I am going to have 5 levels .On each level it would be different the problems. You would have to solve or answer the problems. The levels would be different because you would have to solve different problems so would have to answer each problem correct because you would earn a gallon which would count as 50 points . If you get one answer wrong you would lost 20 points. The players goal is to get all the answers correct. My goal is for them to get through the levels and win the game. does are some of my ideas for my mini game. I would like for the players to start conserving Earth's fresh water. So we could have more fresh water than salt water. I would like them to learn about that its really important to conserve water. So that what my game is going to be about, and what I want the players to learn.
