A rather simple step, remember the story page? Now the next chapter text has been put in place, as well as a cool off text after beating the first boss.
Analog to the ShowChapter routine we add a ShowChapterEnd routine.

The StoryLoop routine is a part of the original ShowChapter routine doing the car movement and wait for button part. We simply reuse the code.
At the .GotoNextLevel label we add this to actually call the new code.
lda LEVEL_NR

beq .ShowStory

jmp .NoStory
