During Gold, we didn't spend a great amount of time adding additional sounds to the game, but added several new sounds to the Break Out Method, mainly when you unlock the gate to the battering ram and when you destroy the spaceport wall. We also added a sound to the crafting UI when you craft an item, so you finally know if you have crafted something. We also wanted to add more sounds to the Market, adding a shop jingle, and a cash register sound when you purchase something. With the music, we needed it to play over the UI, but all the previous sounds had used the play sound 2D which eventually runs out when the music stops, but this also meant we needed to stop this sound when we exited the UI or else it would play throughout the rest of the players experience until it finally finished. For this, we made the piece of music into a variable that we could activate at the creation of the UI and then deactivate when we closed the UI.
