Well, if this isn't a classic Master System game, then what is? I have so many memories with this game, as it was the very first game I played on my SMS (yeah, it was built in). Actually, for a long time, this was the only game I had, as a new game was almost as expensive as the console itself back in those days. So I played it over and over again. Actually, I wasn't the only one who played it in the family. I remember hearing strangely familiar music one time, after I had went to bed (I was about 7 years old). Amazingly, my father and mother were playing Alex Kidd in Miracle World! I don't think they've played video games before or since. At one point, my father had managed to get further in the game than me, and I can remember one morning he had written a note to me, which I read before going to school. He had managed to beat the boss in the (first) castle when playing after I had went to bed, but then his head had suddenly started flying around in the room!!! (I mean the head of the boss in the game, not my father's). I probably thought he must have been joking.
Probably because this game was built in into so many consoles, it probably is the most known Sega Master System game. (And the music in the first level (and many others) probably is the best known gamemusic for any SMS-game.) And including this game with the console probably was a good move by Sega, as it's one of the very best SMS-games. And it's long. This is not a game you are able to finish in 10 minutes. And for a kid like myself, it was magic being able to figure out the game's secrets, like that secret passage under the first octopus in the third level. And finding out that you can actually see what your opponents are thinking during the head, paper, scissors-matches, if you just manage to take that blue ball. Playing this today brings back so many memories... This is what a platform game should be like!
