Devious platformer Stack Zoo asks you to think while you’re leaping around. Beating each level isn’t a matter of reaching the exit without dying, but figuring out how to reach it with the stack of humans and animals that have been allotted to you.
You’re moving multiple characters here, who travel together in an animal totem pole. Starting with just one creature, every time you hop on another’s shoulders they get added to the totem pole, moving together as a single entity with the arrow keys.
