I can now confidently say that I have finished the project. It took longer than expected but I am very happy with the results. I feel as though I have a better understanding of Wwise as a whole now. Looking back on the project, I am glad that I made mistakes as I was able to learn from them.
Here is a video of me playing my finished Cube game.
