A diminutive woolly protagonist soars through a dual-gravity battlefield, tasked with repelling waves of extraterrestrial invaders bent on obliterating the world with their devastating superweapon. The playing field inverts both above and below the screen, creating an unconventional arena where gravity pulls toward paired landscapes—one overhead, one beneath—fundamentally altering how projectiles arc and how the sheep maneuvers. Proximity to either gravitational surface warps the trajectory of shots and slows movement, demanding strategic positioning to eliminate encroaching aliens while managing the creature's hunger by landing on patches of grass scattered across the twin horizons. Maintaining the right balance between feeding and combat proves essential, as starvation or overindulgence costs lives, though meals also restore protective shields. Progressing through 48 increasingly hostile levels requires eliminating every foe before advancing to fresh terrain and amplified challenge.
