3D Slime is a fast-paced game that blends Pac-Man's classic munching with an isometric perspective like Gyroscope. Players control Green Slime, an alien forced by the villainous Rodrick to infiltrate Robocity and collect purple pyramids while evading black bowling balls across pseudo-3D levels with irregular patterns, inaccessible spaces, and varying elevations that require luring the balls away to clear paths.
