Probably the best gba game i've ever played. Another winner by treasure. A love letter to not just Astro boy, but Osamu Tezuka as a whole. The ending sequence is what really made it something special for me. Also just the fact that i think playing this made me better at video games in general. Whenever I died (except for one boss) i always felt like i messed up and i could do better. And I always did.
