Space Cargo minigame - now with time limit and persisted best score

Space Cargo is still in early preview. But we've just added 2 features.

• You have a certain amount of time to complete the level. After that the Alien spots you and you failed your mission
• Score is now persisted. Rescue all the pods in the level. The more energy and time you save, the higher your score.

So you can choose to play slow and carefully. Or burn more energy and move fast. Space Cargo needs a good pilot like you...
