You are given a field of 16 cells (4 by 4).

Each cell is a place to grow vegetables.

First all cells are empty (white).

Once you click on a cell, it becomes black (planted, growing).

Then it grows by itself.

Once you click it once again, you harvest the vegetables, and the cell becomes empty.

Color description:

White - empty

Black - growing, just planted

Green - planting shoots

Yellow - immature

Red - mature

Brown - overgrow

Based on the example (we did during the class) you are to add two features to the model:

1. Add economics

-2 to plant seeds

+3 for harvesting immature vegetables (yellow)

+5 for harvesting mature vegetables (red)

-1 to harvest overripe vegetables (brown)

2. Add speed control

3-4 buttons to select different speed
