Shark.Io
You spawn as a small reef shark in an open ocean arena and your goal is to eat everything smaller than you to grow. Tiny fish give small growth points, medium fish give more, and small sharks give a large boost but fight back. As you grow, you evolve into larger shark species: hammerhead, great white, and eventually a prehistoric megalodon. Each evolution unlocks a special ability: hammerheads get an electric shock stun, great whites get a burst speed charge, and megalodons get a bite that damages everything in a radius. Larger sharks in the arena hunt you if you are still small enough to be eaten, so early gameplay is about hiding in coral reefs and eating fish until you are big enough to compete. Power-ups spawn periodically: a school of fish that restores health, a speed boost for escaping, and a radar that shows the location of all nearby prey.
