I was not very clear, that was on purpose but maybe I was a bit too unclear. So let me explain:
Pressing x helps your aim, maybe you can try it again with this information.
The singing while knocking on heavens door was replaced with playing the piano in front of heaven's door. I had some ideas with Saint Peter and angels but those did not make it.
Like ideas with sound, world building, all had to drop them because I only had a week.
One question for you: What is wrong with the notes? I thought I did everything right.
I played your game too and even though it is not up to me to review it, I must say it left me with the same feeling as my game left you with.
