Additional idea explanation
You can simplify the game by using screens you need to conquer correctly by shooting, talking or making right actions.
For example here on this screen you see that you will need a good trained policeman to shot the robber trying to run away or hide behind the obstacle. But do not shot the civilians that run around in panic. This version would be done as one screen levels where you progress and decide where to go in the story.
And here is the training shooting target example where you progress from junior stage and you get better aim response. That means junior in mission will shot at target correctly but the % of missed will be greater than % of shotted. Make the target pop up with people that give points or take points on the screen. No need to make realistic animations when you are just a beginner in programming.
