what is Twinned Horizons?

Twinned Horizons is a strategy game where building placement and creature populations in a mirrored world affect your civilization's growth.

Build your civilization quickly by placing buildings on a grid while considering the number of creatures in corresponding cells of a mirrored world. The interaction between the two grids influences building strength, requiring strategic planning to optimize your progress.

It sits in the Prestige / Numbers / Management / Automation / Strategy corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
