The superior version to me- a very rare (and ironic) backporting win. This version retains many of the same level themes from the Genesis original, but adds a pick/up throwing mechanic similar to the American SMB2 as well as better level design. There are plenty of secrets to find compared to Genesis Castle of Illusion as well as lucky stars that will permanently boost your health. There's a bit of lag when it comes to picking objects up, and it becomes perhaps a little too easy once you learn how to route the game to get the health upgrades ASAP (since you can also pick the order of the levels you play this time aronud) but it's still a blast through and through. I would consider this in the upper echelon of Master System platformers along with Alex Kidd in Miracle World and Alex Kidd in Shinobi World.
