I wasn't able to navigate by the sounds. The stereo perhaps had me steering left and right properly, but I didn't have a sense of what the "correct" up/down pitch was.
Hey, thanks for trying the game and for the feedback! The idea was that you can ping two sounds one for your current height and one (at a steady pitch) as reference. By comparing the pitches you can tell if you're to high or low. Sadly I didn't managed to teach that concept properly.
