Ant brains
Ants get hungry and eat at the nest, or beg a mouthful from a fed neighbour. They age, and now and then one falls ill and walks out of the nest to die alone, unless a treat cures it. Young ants nurse and old ants forage, and each ant's personal response thresholds shrink with practice, so ants drift into specialties.
A coloured dot over an ant shows how it feels: red is scared, green is unwell, yellow is hungry, blue is resting.
Colony life
Queens lay eggs that pass through larva and pupa stages. Nurses feed larvae, foragers haul seeds home and diggers expand the nest. Soldiers eat twice as much, and without nurses the brood starves.
A few undertakers carry corpses to a midden away from the entrance, nurses carry brood out of floodwater, and the nest stays warm while the surface follows day and night.
The fish tank
Fish make waste. Waste becomes toxic ammonia, and friendly bacteria in the filter turn it into nitrite and then into harmless nitrate. Six water-test tiles show temperature, ammonia, nitrite, nitrate, oxygen and pH, green when it's good, yellow when to watch and red when it needs help now.
The bar along the bottom offers Feed, Net, Siphon, Care and Shop, and you spend coins in the shop, where stars unlock new species.
The reptile vivarium
Start with a leopard gecko, then unlock a crested gecko at 2 stars, a bearded dragon at 4 and a ball python at 6. Each needs a different habitat, so you read its care card first: warm and cool temperatures, humidity, what to feed it and how to handle it.
Feed, Mist, Water, Clean, Gear and Pet keep it healthy, and time is compressed, so a game day lasts a few minutes. The terrarium next door is for pill bugs: keep it damp, leaf-littered and mould-free.
Species and vivariums
Found a colony with the forgiving black garden ant, then unlock harvester ants at 2 stars (big seed loads, slow digging), carpenter ants at 4 (strong tunnellers, smaller colonies), fire ants at 6 (fast, fierce, hungry) and leafcutter ants at 8, which farm a fungus garden if you keep the soil damp.
You can build more vivariums, migrate a colony to an empty one, merge colonies, and host a peaceful or territorial neighbour colony.
War mode and the bedroom
Pet mode is the default. A Rival colony switch in Settings turns on war mode: red ants, raids, and a win or lose ending. The Settings also have a Glass glare switch and a way to erase all saved tanks.
The main menu is a real first-person 3D room built from simple shapes and procedural textures, lit by a sun and a ceiling lamp that follow the real clock.
