How it works
  • Seepas drink from ponds and eat fruit, apples, cactus flowers, pine cones and Siibas
  • The map has nine biomes — grassland, forest (pines), desert (cacti), wetland, tundra (lichen), taiga (spruce), savanna (acacia), swamp (mushrooms) and a marine sea — each with its own food
  • The sea has Fish that graze on coral; Seepas and Suubas catch fish at the shore (another link in the food chain)
  • Ponds, bushes and trees never overlap, and the map grows to fit your device
  • All species inherit speed and size genes that mutate each generation — natural selection in action!
  • In spring, Seepas flock together — they align, group up and keep their distance like a real shoal (toggleable)
  • Summer brings a heatwave — everything dehydrates faster, so ponds become precious
  • Suubas are nocturnal: fierce hunters at night, sluggish and reluctant by day
  • Siibas hide inside bushes and trees at night where predators can't reach them
  • In winter creatures slowly freeze — they huddle near bushes and trees to stay warm. Bigger Seepas resist cold better, Suubas have thick hides
  • Autumn is harvest season — leaves drift down and food grows fast and plentiful, so animals can fatten up
  • Winter is harsh — snow falls and food becomes scarce (most berries and apples stay barren), so populations are tested
  • Aging is optional — turn it off and creatures never die of old age (only hunger, thirst, predators and cold)
  • Migration rescue (optional): a small flock wanders in if a species nearly dies out
