## What is Ikimono Hakoniwa?

Ikimono Hakoniwa is a tiny ecosystem you can watch. Plant grass, place a few animals, and the food chain takes over: they graze, hunt, flee, breed and decline on their own.

- Just watch
No goals to hit. Place rabbits, buffalo, foxes, wolves and crocodiles, then follow the ups and downs on the population graph. Change the speed, toggle day and night, and tune how fast each group breeds. "Place in bulk" in Settings drops 5 or 10 animals at once or fills the map with grass. (Free version: 30 minutes per day; Place in bulk: 5 tries per day.)

- Challenges (18 stages)
Goal-based stages such as growing 40 rabbits, keeping foxes alive under wolf attack, or helping a crocodile ambush its prey. You have limited placements and time. Clear fast and with few moves to earn all 3 stars. (Free version: stages 1-6.)

- Field Guide
Read about each creature and terrain, compare speed, swimming and vision, and explore the food chain diagram. Your own observation records are kept too. Unlock 20 discoveries, like a buffalo herd driving off a wolf.

- Observe tool
Tap any animal to see its age, hunger and what it is doing right now. Tap "Follow" to zoom in and track that one animal. (Free version: 3 times per day.)

- 3 save slots
Keep up to three of your favorite worlds, each with a thumbnail. (Free version: 1 slot.)

- Free and Full Version
The free version includes Just watch mode (30 minutes per day), Challenge stages 1-6, the Field Guide, the Observe tool and 1 save slot.
The Full Version is a one-time purchase (not a subscription) that removes the daily time limit and unlocks all 18 Challenge stages, 3 save slots, unlimited follow camera and Place in bulk, and lets you change the population cap of each species. Buy it from the Full Version item in the menu; use Restore Purchase when you change devices.

- The creatures
Rabbit: the weakest, but breeds fast and swims well
Buffalo: herds drive predators away
Fox: a small hunter that flees from wolves and herds
Wolf: the strongest, but slow in water
Crocodile: hides in ponds and rivers, waiting to ambush

Tap-only controls. The game works fully offline with no ads (the network is used only for the Full Version purchase). Available in English and Japanese.

## Version history (last 2 releases)

### 1.0.1 — 2026-10-03

New
- "Place in bulk" in Settings: place 5 or 10 animals with one tap, or fill the map with grass (free version: 5 tries a day).
- "Predators arriving on their own" in Settings: turn foxes and wolves off individually.
- In free mode, a buffalo herd now fights back against foxes and wolves that catch up with it.

Improvements
- Rebalanced free mode: predators no longer take over, so the rise and fall of grass, rabbits and predators is easier to see.
- Animals now turn smoothly and no longer jitter when walking or fleeing.
- Adjusted the goals of a few challenges to match the new fleeing behavior.

Bug fixes
- Fixed animals crowding the edges of the screen or getting stuck at the border.
- Fixed grass sometimes not growing back for a while after being eaten down.
- Fixed crocodiles getting stuck where a pond meets the river, or chasing prey in a different pond.
- Fixed crocodiles sometimes starting on land, and grass growing in the river, at the start of free mode.
