Yoku's Island Express

This is an adventure-platformer in which players assume the role of a beetle named Yoku as he explores an island and its caves. Players run, jump, collect special items, and engage in battles with fantastical enemies (e.g., giant eels, spiders). Battles are depicted in a pinball-machine-style layout, in which players bounce and shoot Yoku at the creatures. Enemy bosses and monsters cry out in pain when struck, and one boss emits splashes of yellow when hit/defeated. One scene depicts Yoku rolling a ball of dung, and another shows a brown “poo coil” surrounded by flies.
