About Age of AGI
An evolution war game fought down a single lane, in one continuous match through six ages. Train units at your base and send them up the line, build turrets behind them to hold what you take, and push toward the enemy base while stopping theirs from reaching yours.
Fill the experience bar and your whole army evolves: better units, better turrets, and a stronger special you call down from the sky. Each age changes what both sides field, so a line that was holding comfortably stops holding the moment the other side moves up. Reach the AGI Age and the battlefield moves off-world.
The whole game is the spending decision. Put everything into units and your turrets fall behind and the line comes back at you; put everything into turrets and the line never moves at all. Mouse only, and one match runs start to finish without a menu in between.

The prompt behind Age of AGI
Make a single-lane evolution war game: two bases, units walk at each other and fight, kills pay gold, buy units, upgrade the base, add turrets and turret slots, special attacks, and ages to advance through — with progression. Balanced with a headless bot simulation before the first play-test.
