Move around with the arrow keys.
Change your tools from the number keys (1 - 4).
The goal of the game is to have a thriving economy build up from your plantation. Hoe the ground, plant and water the seeds. Go to bed and wait a day. Harvest and your products and cash in. Repeat on the next day. Be careful not to run out of money or to go to sleep without watering the crops!
Keep on living in this sad capitalist reality until the end of your days.
