Yeah, Alex was SEGA's answer to Mario.
Alex Kidd is a really interesting video game character and series. I like to think of him as the Oswald the Rabbit of SEGA. In his heyday he was the star, given loads of press and a number of games. Then when Sonic arrived, Alex Kidd was quickly kicked to the curb and the flaws of the series and character became very apparent.
I wasn't aware of Alex Kidd in the 90's, since I was a Sonic kid, but I did learn more about him in the early '00's and played most of his games. They're fun, no doubt, but they are missing something. I think that "something" is what Sonic has and Alex doesn't have. Alex Kidd felt too difficult, he was too prone to death. One hit deaths kill a game, in my opinion. I hate walking on pins and needles when I play a platformer. The best platformers take more than one hit to kill the player: Mario has a maximum of three, Sonic varies but you're pretty much assured to live if you have a lot of rings.
The punching mechanic is kind of lame. It's not the coolest attack. Ristar, however, has a similar method of attack but it's far cooler. Stretchy arms help.
Anyway, I do like Alex Kidd, if only for the history behind the series. I love how SEGAGAGA utilized him:

Poor guy. I also really liked his cameos in SASASR and Superstars Tennis. He deserves the recognition. His games may be so-so, but the character was fun to play as in those instances.
