A pretty decent NES game and has a strong chance of being my favorite of the console's library. It's a really fun time but the last two castles get pretty tough. Man, I really wonder what it would've been like if this got translated and released in the US back in the day, or if Takamaru did make the cut for being a smash fighter that one time. Now that this is on Switch online I'd recommend playing at least the first castle.
Final score: 7/10
