## What is BunnySim?

BunnySim is a pixel ecosystem you watch more than you play.

You shape the land and feed the loop. The animals do the rest. Nothing is scripted and nothing is on rails — every chase you see is the same handful of rules colliding with the map you drew. Each run starts from a fresh seed, so the same meadow never plays out twice. A boom, a crash and a recovery can all happen while you wait for a bus.

DRAW THE LAND WITH YOUR FINGER
Paint a river across the grass and it becomes a real wall: nothing walks on it, nothing spawns on it, and every animal routes around it. Plant bushes for cover, erase water back to grass, and save a map you like to play it again.

CARROTS ARE THE WHOLE ECONOMY
Rabbits notice a carrot the moment it enters their perception circle and hurry toward it. Carrots keep sprouting, so the meadow always has a reason to move. A rabbit that eats enough of them climbs a tier.

FOXES THAT ACTUALLY HUNT
A fox sees further than a rabbit but turns slower, so it wins by ambush and by cornering. Go too long without a catch and it starves. Apex foxes stop to scent the air and follow a trail along the ground.

THREE TIERS, TWO APEX STRAINS
Eat enough carrots and a rabbit turns golden, sees wider and leaps rivers. Catch enough rabbits and a fox turns deep red. At the top each species splits into two named apex strains that play completely differently — eight animals in all.

A POPULATION GRAPH, LIVE
The bottom bar plots rabbits against foxes while you watch. Boom, crash and recovery are visible as they happen, not in a summary screen afterwards.

CREDITS YOU EARN, NOT BUY
Ten carrots eaten gives you one carrot to place. Ten rabbits caught gives you one fox to place. That is the only currency in the game.

SANDBOX MODE
Turn off the clock and the scoring and just build. Place what you want, watch what happens, and stop when you feel like it.

TUNE THE RULES
Open the parameters screen and change hunger rates, breeding speed, perception range, carrot growth and more. Save your favourite setups as presets, or load one of the built-in ones and see the same meadow behave like a different game.

LEADERBOARD, IF YOU WANT ONE
Signing in is optional and the whole game works without it. Sign in with Apple or Google and you get a nickname, a profile picture and a place on the global longest-run board.

COMFORT AND CONTROL
Play in portrait or landscape, with an optional rotation lock. Blood stains left by a catch can be switched off in Settings. The game speaks 18 languages and always starts in English until you pick one yourself.

Free to play with ads between runs. One optional in-app purchase removes advertising permanently — a one-time payment, not a subscription, tied to the account you sign in with, so it restores on a new device.

No accounts required. No timers. No energy bars. Just a small meadow, a few hard rules, and whatever happens next.

## Version history (last 2 releases)

### 1.1 — 2026-11-06

NEW
• DNA Mutation: earn DNA from your runs, unlock genes and equip up to 4 per animal to shape how rabbits and foxes evolve.
• Weekly leaderboard: a fresh ranking every Monday, right next to the all-time board.
• Weather: trigger rain, wind, storms or fog from the new Environment menu. Each one changes how animals track, sniff and see.
• Fenrir: too many alpha foxes will call a wolf out of the snow, and it hunts them down.
• Boosts: catch 50 rabbits to charge up Bountiful Harvest or Bloodlust.

CHANGED
• Scored runs are now pure simulation: animals and carrots can only be placed in sandbox, and you choose where the bushes go.
• Tougher balance and many fixes.
