Thank you for your honest feedback!
This game certainly won’t be everyone’s cup of tea, but I think you are pointing a few hard UI design and balance issues that need fixing. So that is very helpful :)
About music & sound: absolutely, this was just not a level of fidelity I had in scope for the prototype. Although thinking about it, adding a 3rd-party music asset and a few more beeps here and there probably would have not been that much work.
