(Tetsuwan Atom)

Tetsuwan Atom (known globally as Astro Boy) is a side-scrolling platformer developed by Zamuse and published by Banpresto. Based on Osamu Tezuka’s iconic manga and anime series, the game follows the adventures of Atom, a robot boy created by Professor Ochanomizu. Tasked with using his advanced capabilities—including super strength, rocket-powered flight, and hidden weapons—to protect humanity, Atom must navigate eight distinct missions ranging from haunted houses to space stations, tackling platforming challenges and diverse enemy threats.

Mechanics & Upgrades: The game features a progression system that ties directly into the character's robot nature:
- Health System: Atom starts with three health units (hearts), which can be upgraded to a maximum of six through collection.
- Support System: Players can collect Small Radios throughout levels, which summon Atom’s sister, Uran. She provides essential health items or extra lives, serving as a tactical support mechanic.

Combat Capabilities: Atom’s versatility is reflected in his move set: he can use standard punches for close-range encounters, charge his rocket boots to hover, or execute a powerful air-dash attack to bypass hazards or strike enemies.

Stage Variety: The level design draws heavily from the Astro Boy aesthetic, featuring varied environments like large, trap-laden pyramids and technologically advanced space stations, each culminating in a boss battle that tests the player's mastery of Atom's mobility.
