Press the start key and follow your pet bee's instructions. In the beginning it's telling you how to play. I know it's ridiculous to listen to your pet bee but just DO IT. Use the arrow keys to use the bee leash and move your bee around. Press the space bar to take the bee leash off. Lead your bee to the bed or the nectar bowl (both on the bee platform) to fill up its hunger/thirst and sleep. The bee chair just looks nice and is fun to get your bee to sit in. Press 1 and 2 to move between the Flower Bed and the Flowers. 1=Flowers, 2=Flower Bed. Your bee's hunger/thirst and sleep will start at 0, try to keep both below 10. Your pet bee will buzz once in a while.
I got the idea from esba23's virtual puppy game. LATEST UPDATE: You can now move from the Flower Bed to the Flowers by pressing 1 and 2.
