Create a new object called life controller. It does not need a sprite as we will control the drawing itself using the drawing event. Make the depth -10000 so it's in front of everything else.
Add a Create event
Add a Draw event:
Add the life controller to your room.
Test it out - does the score panel look like this when playing?
Add a Step event that checks the score. When the player has more than 200 points, the game ends. (normally you'd set the amount to much higher, but we're keeping it low so you can easily see it works). They'll get a message and be able to put their name in the high score table and restart the game.
If you test out your game, hold the Space Bar to keep shooting and go back and forth along the bottom of your screen to get the score up quickly. Once you get the score to over 200, you should see the high score table.
