They call themselves "Homo sapiens", but they are actually "naked apes". "Human Zoo" is an adventure game with a narrative. You will play as a little monkey, from a reptile to an upright human, changing its biological form every time it passes through a level. Jump over the jungle, study books, kill partners, reach the temple, wear the angel ring that symbolizes divinity, and achieve the consummation of self-cultivation. However, the game restarts again and everything is just a lie. I hope to leave each player with philosophical thinking about human and animal nature. - "You are part of a unique and unparalleled species, please understand your animal nature and accept it."
