I sweat this game has the best Zelda music. The GB limitations just made them work that much harder to make the music memorable. There are subtle switches and tweaks you only catch because you've been playing this series for decades like me.
Note I was 8, i think, when I first played Zelda in 1987, when we got our NES for Christmas. So it's been neat seeing him want to take on Zelda games. He tried the oracle games and minish cap and some BOTW and Windwaker, but this one looks like its sticking. ALTTP will have to be next.
