Pretty ambitious for the time, though it's definitely surpassed by Zelda 1 and Metroid 1 from the same year. Interesting mix of 2d platforming, a Contra-style run-and-gun, light RPG mechanics, and some Zelda-like dungeons. Unfortunately it does feel held back by the limitations of the NES and archaic game designs of the era. A Kid Icarus sequel on the SNES probably would've gone so hard.
