Astro Boy: Omega Factor (Known in Japan as Astro Boy • Tetsuwan Atom: Atom Heart no Himitsu) was based on Astro Boy, released in 2004 for the Game Boy Advance after the Anime's 2003 Reboot. It was developed by Treasure and Hitmaker and published by Sega. Many consider this game an aversion of The Problem with Licensed Games, and a fitting tribute to Osamu Tezuka. There are also a few levels where Astro exclusively flies. He relies on his finger laser for offense, but can dash and use his specials normally.
