Hey, thank you for feedback! As I already mentioned in another answer to a comment - due to my own personal time constraints and this being the first project in which I would have implemented sound I wasn't able to get SFX and a theme for the game working. As of right now I already have an updated build of the game with sounds, it just isn't downloadable yet.
Could you elaborate what you exactly mean by saying "it feels like an unnecessary thing to monitor"? Do you mean that it was just too difficult or that it felt "unnecessary" in a way? It was kind of my plan from the start to couple both things together, because it made more sense with the one button theme and I thought it would make for an interesting puzzle mechanic.
