Game Mechanics

These are the basic aspects that create the game.

Tools
These are various devices you must use in the game in order to progress

Sun
This is the main currency you will use in the game in order to place more plants. You can either collect it from the sky in various degrees of cost, from various sun-producing plants, or from other sources, like tombstones or certain zombies

Seed Packets
These are the tools that you use to place a certain type of plant. The type you click on is the one that is placed. They each require some degree of sun, and have a cooldown period before you can use them again.

Shovel
Allows you to clear a tile from an unwanted plant. Can be upgraded to cooldown quicker, refund some spent sun, or move plants.

Areas
These are the main "worlds" you play in. They each have unique unlockable plants and power-ups, zombies, and stage elements

Plants
These are the player's primary defenses against the zombies. You must utilize their abilities in order to defeat the zombies each stage, and to complete stage objectives.

Zombies
These are the player's primary enemies. You must get rid of them and prevent them from reaching your house, or else you lose the level. Their are different types, each with unique defenses that you must counteract in order to succeed.

Power-Ups
These are the last-resort defense you can use against the zombies. They're very strong, but are expensive. Use them wisely!
