Ah thank you for playing our game and all your good feedback! None of us are very familiar with audio design so it was a bit of a struggle. We did have a cool idea that the scaling would play notes on a music scale (different one for each character) but we tried to implement the one on a piano and it sounded really off. We tried to look for something different but it was cutting it very close to the deadline so we decided to just leave it out sadly enough.
I loved the audio in your game so if you have any suggestions how to implement this well please feel free to let us know :)
