EvoWorld.io (formerly FlyOrDie.io) drops you into an ecosystem as a fly and asks you to climb a food chain of more than forty animals. Eat what's below you, avoid what's above you, and evolve — each stage changing what you can eat and what can eat you.
It's more of a survival game than most .io entries: there's water to drown in, land to suffocate on as a fish, and predators that specifically hunt your current form. Knowing the chain is the whole skill.
More than forty, forming a food chain from a fly up to apex predators. Each evolution changes both what you can eat and what hunts you.
Because each new form has different predators and a different habitat. Check what eats your new form before continuing to hunt in the same place.
