I love this game so much. Played it for way too many hours over the years, including a big stretch of just exploring while using the game genie to give me invincibility and super jump. Incredibly good game.
Don't know when I first completed it. Some time in the nineties, I guess. I've completed it several times, over the years, including some time in late 2010--I've got a note in my game journal from 2010-11-14 that I completed the game 'a couple of weeks ago'.
Moons
There are seven 3-Up Moons in the game, one in each world except Star World and the Special Zone:
The Lunar Dragon category requires the player to complete every exit, collecting each of these moons, as well as at least 5 dragon coins on those levels that allow it. Here's a run by mystakin from GDQx 2019.
