The object of the game is to save everyone in each level who needs help and to repair everything that was damaged, in a limited amount of time.
The goal of each level is outlined on the start screen and in the upper-right section of the level.

Tap a resource or an object to plan a task.
Rescuers will complete the tasks, but you will need to give the orders correctly in order to complete tasks in time.
You will need resources (Food or Tools) to complete the tasks.

The Resources can be gathered in the level or received from Boosters.

If you don't have enough resources to complete a task, the game will tell you the type of resource you need and how much of it you need.
