In level mode grow your plant to the goal plant size or exterminate all of the drones depending on the level.

In endless mode grow your plant as big as possible.

Change the game mode in the options.

*Version 1.1*

ADDITIONS
-*Saves what level you've reached in the game, when you load it up again you can play any level you've gotten to(select level in titlescreen options menu when levels game mode is selected)*
-Music
-Sound for sprouts spawning
-Sound for plant needing water

FIXES
-*Bulbs now work correctly*
-Rain sound for clouds no longer breaks and gradually gets louder the more rain clouds there are
-You can now only evolve a stem into a root if there is no sprout on it, if there is a sprout you can click regress then click evolve to root
-Preloader loading bar now displays correctly
-LOTS of other random small fixes

CHANGES
-Goal plant size in levels game mode now slowly increases each level
-Adjusted cloud and sun amounts for jungle and desert levels
-Clouds now vary the amount of time they last for different levels(on jungle they spawn frequently but don't last long, on desert they spawn infrequently but last longer)
-Adjusted and made larger the PlantSize and AntKills text
-Made almost all of the buttons bigger(*including the stem menu buttons*)

If the ants kill the main plant then the plant dies, protect the plant by clicking on a stem and a menu will pop up to either spawn a sprout or evolve the stem.

You can only evolve a stem into a root if it doesn't have a sprout on it. Roots will make the plant spawn more stems at their location towards the sun. Stems can't grow over other stems though.

The green bar is the stem's health and the purple bar is the nutrients for the entire plant. Nutrients are used to spawn sprouts or to evolve the plant.

When clicking on the plant or a root to blue bar is the water for the plant. If the water runs out the plant will start to take damage.

Check the ingame manual's last page for some good ideas on basic strategies to grow with the plant.
