Now that you're done with the game you can change it up a little. Here are some ideas

1. You can try to fix the problem at the end of the Detecting Collisions Card.

   Hint: Try using a boolean and checking its value to see if the player should be moving.

2. Implement keyboard controls for the spaceship!

   Hint: You used the keys for controls in the first tutorial, take a look at that.

3. Try getting another asset from the resources listed on the front page. Try and create them like you did with the asteroids.

   Hint: You need to make your asset into a prefab first! Go back to the first tutorial if you don't remember how to make a prefab.

4. Learn more about the programming language you have been using with Unity: C#. Here is a link to Microsoft's Beginner tutorial dojo.soy/C#Tutorial.
