I learned playing the piano for several years (some time ago) and I still struggle with these 2 dimensions hard. which makes your wonderfully crafted game give me PTSD like flashbacks and I am really sorry for it. it looks good, it plays well, it sounds great - but it's still hard for me to be in the same room with it. maybe it can be a useful to me as a tool for behavioural exposure therapy. I will get back to you, if my therapists aproves ;-)
