Sunman is a single-player action platformer game in which players control the titular hero, navigating through various levels by running, jumping, punching, ducking, and flying. The game features a mix of ground-based and aerial combat, with some levels allowing players to shoot laser or heat vision from their eyes during side-scrolling flying segments. In this game, the storyline is set in a universe where Sunman must traverse five distinct scenes, each divided into four areas, culminating in a boss fight at the end of each section. The game was developed for the Nintendo Entertainment System and was planned for release in 1992, but it was ultimately never officially published or announced, making it a rare and unreleased title. It stands out with its unique gameplay mechanics that include flying by simply pushing up and the ability to engage in shooting segments during flying levels. Its design is reminiscent of Sunsoft's Batman series, offering a blend of platforming and shooting elements, with advanced features like multiple areas per scene and boss battles, providing a diverse and engaging experience for players interested in classic action-platformers.
