To start, hover over a landform to see what it is. Hold the mouse down to see what lives in it (to translate the names, go to the de-translator). Hold up to see how much it costs and how much money it gets per sec. Press space to see what recsource it gives you. Click/hold the left or right arrows (maybe a couple times) to buy it (if you have enough money). Every time you buy something, your pollution meter goes up. Click the down arrow to reduce it (for $100). Click the ship and it will give you a deal. If you bought the place that gives you the resource they want, click the offer, if not, click the background.
You can't buy everything yet or see its resource, etc. etc. Endless ocean for music!
