BASICS

Buildings

Buildings sit in fixed slots on the Crawler and cap at level five. The Barracks gates the rest, so it is nearly always the right thing to raise first.

Upgrade timers

Every upgrade is a timer, and every timer in this game can be shortened with Temporal Catalysts. A wait you cannot boost is a bug, not a design choice.
