Eradicate!!!

Goal: You are a mad gardener who prefers silence. Get rid of all the plants and leave an empty world. 

Controls: You can move with arrow keys and can place fences with "x" so the plants don't grow everywhere.

Gameplay: Every plant has a different characteristics in growth and nutrition value (unlike wheat grass is not very good against hunger). Strategize what to eradicate first and where to place fences. But be fast because you'll get hungry soon.
