It plays like a combination of the 1st Zelda game and Dragon Quest. An over world map you can fight on, use your items, enter towns or caves. The level up system has some very Dragon Quest vibes, same with the shopping and using Inns in towns.
It’s been a good escape from the newer stuff. Getting lost in an NES game I’ve never played before has been fun thus far. It’s worth a look. Arcus does a great play through of it, and at the time, was also his first shot at the game. https://www.youtube.com/watch?v=FlJm5k4EYbY
