1981 DECO Cassette System arcade action game, where DECO Kid flies and punches enemies in side-scrolling environments. Ahead of its time, it set precedents for mechanics such as multi-directional scrolling, bosses, energy bars, debris, invincibility, and score combos.
The character of DECO Kid is notes to essentially be a copy of Astro Boy - much more so than the later Mega Man, in fact.
