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, drops piles of grass, or fills the map with grass. Your Just watch world autosaves, so it is still there when you reopen the app. (Free version: 30 minutes per day; Place in bulk: 5 tries per day.)

- Explore a bigger world
Use Map size in the Map menu to make the free-mode map 1, 2 or 3 screens wide. Pinch to zoom, and use the Move tool or a two-finger drag to look around. Tap the minimap in the lower left to jump straight to a distant herd. The bigger the map, the more creatures it can hold. Groves near the water, rocky ground and raised plateaus (on Huge) shape the land, and thirsty animals drink at the water's edge.

- The cycle of life
Where an animal's life ends, bones remain, slowly return to rich soil, and flowers bloom. Little birds eat from fruit trees and carry the seeds far away, so new trees take root. Animals gather under the trees for fallen fruit, and a fox may be waiting.

- Make a map
Place rocks, trees, fruit trees, ponds, a river and plateaus anywhere you like. Name your ponds and plateaus, save the land to My maps, and start fresh on it any time. (Free version: 1 My map slot.)

- Names and families (Full Version)
Give an animal a name, and its children and grandchildren join the same family and inherit its markings and personality. Follow how many generations it lasts on the family tree. When a named animal's life ends, a name flower blooms there; pick it to keep a pressed flower in the album.

- Challenges
Goal-based stages such as growing 40 rabbits, keeping foxes alive under wolf attack, helping a crocodile ambush its prey, and "The Cycle of Life" stages about flowers, forests and families. You have limited placements and time. Clear fast and with few moves to earn all 3 stars. (Free version: stages 1-6 and the free trial "Keep a Family Going".)

- 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. Collect discoveries, like a buffalo herd driving off a wolf or a tree growing from a seed a bird carried.

- 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 and the free trial stage, the Field Guide, the Observe tool, Make a map, 1 save slot and 1 My map slot.
The Full Version is a one-time purchase (not a subscription) that removes the daily time limit and unlocks all Challenge stages, names and families, 3 save slots and 3 My map 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
Bird: eats fruit and carries the seeds, spreading the forest

Simple controls: mostly taps, plus pinch to zoom. The game works fully offline with no ads (the network is used only for the Full Version purchase). Available in English and Japanese.
