PREVIEW: Let's create another basic arcade or phone game. This game only has one control but it's still challenging!
- Click Run to try playing the game you'll create!
- Press the spacebar to make the dinosaur fly! Make sure to avoid the obstacles to gain points.
- Click Submit and Next when you're ready to start coding!
