Our math game is coming along nicely. Unfortunately, we have to move on soon. The project has served its purpose to demonstrate some fundamentals of Java programming as well as some key Android features. Now we need to start introducing some more game-related topics.

Before we go on, there are two really easy things to make our game a bit more cool and complete. In case you are wondering about the High Scores button, we will see how that can be implemented when we look at our next game project in Chapter 5, Gaming and Java Essentials. You will then have enough information to easily come back and implement high scores on your own.

The other feature that would really round off our game and make it more playable is an overall or per question time limit. Perhaps even increasing the score based on how quickly the correct answer is given will help. We need some new Java tricks up our sleeves before we can do that, but we will see how we can measure and respond to time in Chapter...
