Areas (Main)

These are the main "worlds" you can play in. Each has their own stages; unlockable plants, tools, and power-ups; and new zombies, minigames, and bosses!

Objectives
These are the accomplishments you must complete in order to win a certain  stage. If you don't, then you lose the stage and have to restart.

Some objectives are


 * Defeat the zombies - Defeat all zombies in the stage.
 * Produce # sun - Use sun-producing plants to create a certain amount of sun.
 * Don't lose over # plants - Don't have at most # plants be defeated, through shoveling or zombie bites.
 * Have a maximum of # plants - Don't have at most # plants be planted onscreen at a time.

Stage Elements
These are the parts of each area that make them stand out. They effect plants, zombies, and other aspects of the game, like sunfall and seed packet recharge.
