Very cool project. Kudos for making it mobile friendly too. The world appears to be infinite, why not make the trees also infinitely procedurally generated?

Very cool project. Kudos for making it mobile friendly too. The world appears to be infinite, why not make the trees also infinitely procedurally generated? Then you could get the experience of "do I stay here where the sound is good, or do I explore in search of something new, and perhaps better?" With a few more instrument types, and variable density, you could in theory create an auditory "Library of Babel", where any song or sound is in theory possible to discover... If you only find the right combination of plants. Also you should add animals, like turtles and rabbits - the sound would change because instead of being stationary, they move towards/away from you. Different types of animals could have different movement patterns, producing a variety of effects.
