Fish Eat Fish drops you into an open ocean as a small fish you control in real time - move the mouse, drag on touch, or use the arrow keys, and your fish swims that way continuously, no clicking or holding required. Glowing plankton drift everywhere for an easy, steady source of growth, and other fish of every size wander, flee, and sometimes hunt around you. Eat anything clearly smaller than you and you grow - gradually at first, then more slowly as you get bigger, since growth is based on area rather than a flat number, so there's always another fish worth chasing. Anything clearly bigger than you is a threat: touch it and you lose one of three lives, shrink back down, and get a brief moment of safety before you're back in the water. The ocean gets more dangerous the longer you survive - the first ten seconds spawn nothing but easy food, bigger fish start showing up around the half-minute mark, and after about a minute the biggest ones - drawn as dark, elongated, shark-like silhouettes you'll recognize on sight - stop wandering and start actively hunting you down. Survive five minutes and food gets scarcer still, forcing you to hunt rather than graze. Your score combines fish eaten, plankton eaten, and seconds survived, with your best run saved right in the browser.

How to play

1. Move the mouse, drag your finger on a touch screen, or use the arrow keys / WASD - your fish swims continuously toward wherever you point.
2. Eat the glowing plankton dots and any fish clearly smaller than you to grow bigger, bit by bit.
3. Stay away from any fish clearly bigger than you - touching one costs one of your three lives and shrinks you back down.
4. Watch for the dark, elongated predator fish that appear after about a minute - they actively chase you, unlike the smaller fish that just wander.
5. Keep eating and dodging to push your score higher; your best score is saved automatically for next time.

Why it is not just clicking

Most small browser games about a growing creature either stop the action to make you wait (hold a line taut, time a swing) or hand you a fixed-size arena with nothing that changes. Fish Eat Fish keeps you moving every second and makes the ocean itself escalate: for the first ten seconds everything you meet is safe to eat, by thirty seconds you have to start checking size before you swim toward anything, and by a minute in, some of the fish around you have stopped wandering and started hunting you specifically - a layered difficulty curve that teaches itself without a single line of instruction text, just by what shows up and when. Growth is area-based rather than a flat number per bite, so getting bigger naturally slows your own growth rate and keeps the chase interesting at every size instead of letting one lucky streak end the challenge in seconds.

How hard is it?

There's no difficulty selector - the ocean ramps up on its own as you survive longer, which is measured, not guessed: the first ten seconds spawn only fish smaller than you, bigger fish start appearing around thirty seconds, hunting predators switch on after about a minute, and food thins out after five minutes of survival. A six-year-old can manage the steering immediately; judging which fish are currently safe to approach is the part that takes a little practice, and three lives with a brief safety window after each hit keep a bad judgment call from ending the run instantly.

Is it right for younger players?

From about six: the controls are a single continuous motion (point where you want to go), but recognizing 'this one is bigger than me' at a glance, and reacting before it's too late, benefits from a bit more hand-eye coordination than a simpler hold-and-wait game. There's no violence beyond an oversized cartoon fish 'catching' a smaller one - no blood, no screen shake, no loud jump-scare sound.

For parents

No ads, no sign-up, no purchases, and nothing to install - it runs entirely in the browser, and the only thing saved is a best-score number, kept on your own device. Every piece of art is simple vector shapes drawn for this game, and every sound is a short, synthesized tone - there's a sound toggle, and even with sound on there's nothing sudden, loud, or jarring. Losing a life pauses nothing and shows no graphic imagery - the fish just shrinks and gets a moment of safety before swimming on, and a full game ends with a plain score screen and an immediate retry button.

In the classroom

Fish Eat Fish is a clean, concrete example of relative comparison as the entire mechanic: there's no abstract rule to memorize, just 'is this bigger or smaller than me right now,' re-evaluated continuously as both the player and the other fish change size and position. It also demonstrates escalating difficulty done through content changes rather than a ticking clock or an explicit level-up screen - the game quietly introduces bigger fish, then hunting behavior, then scarcer food, at measured points in time, which is a useful contrast to games that signal difficulty only through an explicit 'Level 2' banner.
