My take on designing sound for an existing property.
When designing the sound, I decided that everything in this game actually "exists" in the world. To me, this is a kid playing in his backyard with a puppet. This means realism. Any object that isn't in the game UI is actually there producing sound as this kid plays. For example, the cardboard water moving on a mechanism doesn't sound like water, it sounds like the crank that moves it. The UI elements are the only non-realistic sounds.
My big focus on the music was to give voice to the sense of playfulness in the game. I decided to challenge myself by fixating on making the 5/4 time signature playful. In order to achieve this, I created a motive with a few variations on vibraphone supported by bass piano and natural percussion.
