Welcome to the biggest Idle Terra update so far! Version 1.2.0 — The Colony introduces an expanded life-simulation system, a deeper economy, brand-new colony districts, and a redesigned approach to developing your base. Your settlement is no longer just an industrial outpost — it’s now a living colony.

New Colony Stat System

A full set of new colony parameters has been added:

Core Stats:

Population
Health
Entertainment
Justice
Ecology
Science
Commerce

Derived Stats:

Morale
Corruption
Taxes

Every building now affects these stats in one way or another, creating deeper and more meaningful strategic decisions.

Population Growth Population growth now depends on Morale and overall living conditions.

Up to ~500 colonists, growth is relatively stable.
Beyond that, you’ll need to significantly improve comfort, infrastructure, and ecological conditions to attract new residents.

Your colony is now a living ecosystem that reacts to your management.

Colony Mode and 9 New District Buildings

The Plateau area can now be switched between:

Plateau (Industrial)
Plateau (Colony)

In Colony Mode, you can construct nine new district buildings:

Residential Blocks
Living Districts
Green Quarters
Commerce Quarters
Leisure Districts
Medical Quarters
Research Districts
Security Sectors
Park Sectors

These buildings do not produce resources, but they provide significant boosts to Health, Entertainment, Justice, Ecology, Science, and Commerce.

They require substantial investment, but offer strong long-term rewards through higher taxes, improved population growth, and a stronger economy.

(Balance will continue to evolve — but the core system is now established.)

Tooltips have been added to important interface elements to give new players basic explanations and help them understand the core mechanics more easily.

If more tooltips are needed — feedback is welcome.

Resource Trend Indicators

The resource panel now displays arrows showing whether each resource is increasing or decreasing. A simple but very useful addition for managing your economy.

GUI Layout Improvements

Several interface panels have been repositioned and adjusted for better clarity and usability.

Additional Changes

Improved map seed generation algorithm.
Various optimizations.
Several minor bugs fixed.
