Japanese version of Astro Boy on GBA. Solid action platformer faithful to the character. Less rare than Omega Factor but equally enjoyable to play through.

Is Astro Boy - Tetsuwan Atom - Atom Heart no Himitsu still worth playing in 2026?
A Japan only action game from Sega, this title stages Tetsuwan Atom, Osamu Tezuka's mythical hero, in clashes against robots and mechanical threats. The snappy gameplay blends aerial combat, shooting and fast movement, faithful to the manga's spirit. The polished presentation and vivid colours flatter the machine, even if the structure stays classic and a bit repetitive. The language barrier slows access. For an Astro Boy fan or someone curious about Japanese licensed action, the title keeps a likeable retro charm.
