I had to "check puzzle" once. I would've never seen my mistake (RING for WING - in my mind play = ring (as a tune??) and ear side = literally ring because earring). Could you explain the clue for ANGOLA?
ANGOLA: A (Austria) ALONG (down) reversed (backs) to give AGNOLA with N (new) moved up (promoted). I appreciate there’s a lot going on there. Hope you enjoyed the puzzle though! This was my first second ever creation
