The sound and music design deserves special mention. Not only does the soundtrack to Valley perfectly match your surroundings, it ebbs and flows throughout the game in response to your movement. Action sequences will trigger more rousing music, such as battles, but there are also segments of the game where youíre simply exercising your powers. The game constantly uses audio to draw your focus to strange and wonderful aspects of your surroundings. As just one example, the booming bass sound that you hear when hitting the ground after a massive leap never gets old.
