Narrative Structure

My plan was to have a narrative that split into choices at key "dramatic cliffhanger" moments. The player then chose a method by which the main character solved the dramatic problem. The original plan was to be a early set up leading to a dramatic cliffhanger moment that would split the story down two seperate paths. Each one culminating in a cliffhanger choice. leading up to 4 seperate conclusions.
The original basic story structure was thus
Introduction to the main character and a dramatic conflict. His girlfriend being kidnapped by his arch nemesis. This was to lead to a space battle as the hero raced after his nemesis. The battle would culminate in a cliffhanger choice of fight or flee. If you continued to fight, the player would be joined by his girlfriend's father's pilots. And the story would continue in space as they lead an attack on the bad guy's mothership. Ending in a cliffhanger of whether the hero would teleport onto the ship to rescue his girlfriend and let the bad guy away, or continue to fight and having the mothership blow up potentially losing his girlfriend but finally defeating his nemesis.
The other plot line would have the hero getting shot down and captured by the villain's men. The hero would be taken to the mothership as a prisoner, about to lose his life. This is the next cliffhanger moment. The player could then choose to make use of a hidden laser gun to fight their way out to rescue the princess, or to use a teleportation device to escape his situation, to rescue the girlfriend again later. So 3 choices and 4 endings.

 However due to time constraints the first plot thread in space ended early. Instead of there being a choice of blowing up the mothership or teleporting aboard. The plot continued to the mothership exploding with the villain escaping with the hero's girlfriend on an escape pod, and ending with the good guys chasing the escape pod to rescue the hero's girlfriend. So now the narrative features 2 choices with 3 endings.
