5. 5

   Click the 'Remix' button to make your own copy

   
6. 6

   Start by selecting the 'Robot' sprite

   You'll notice this sprite already has some code.

   
7. 7

   Add this code so the robot can move to the right when you press the right arrow

   The forever loop makes sure you can continue to move while the game is running

   
8. 8

   Now add another condition so that the robot can move to the left

   
9. 9

   Test out your code!

   Can the robot move left and right when you press the arrow keys?

   
10. 10

    Now switch to the 'UFO' sprite and add this code to make it move around

    
11. 11

    Then add this code so that if the UFO touches the robot, the game stops

    The 'stop all' block stops all the code in the game

    
12. 12

    Finally click on the 'Crystal' sprite

    This code will make a new copy of the crystal every second

    
13. 13

    To make the clones appear, add this code

    We can use the 'pick random' block to make them appear in random positions

    
14. 14

    Press the Green Flag!

    Do you see the crystals appearing?

    
15. 15

    Next add this code so that we get one point on our 'Score' variable each time the robot gets a crystal

    
16. 16

    To make the game a bit harder, we can add this code so the crystal clones will disappear after a few seconds

    Great work! Press the Green Flag and have fun playing your game
