Thank you for this, I really appreciate the detailed and constructive breakdown. The slow thing does seem to be the resounding feedback but you brought my attention to more things that I can work on. My friend actually said the same "left and D" thing to me and I thought that was really interesting because it honestly hadn't even occured to me until he mentioned it.
The music is probably the most afterthought part of the game haha, so something to work on there as well
