Rules:
1. You must complete the required tasks in each mission before moving on to the next.
2. There are certain required "operations" that you need to complete.
3. You will earn points for each task you complete. If you are on Mission 3 you can still go back down to Mission 1 and work on those tasks, they just aren't worth as many points.
4. Level achievements are based on points, not on missions.
