Upgrade whatever is causing your losses first — treehouse survivability when you take damage, turret quality when waves clear slowly — and bank offline income to spend in planned chunks.
An upgrade order for your treehouse defense: when to upgrade versus roll, how to judge 'behind or ahead', and cash habits — principles over invented tables.
Upgrade whatever is causing your losses first — treehouse survivability when you take damage, turret quality when waves clear slowly — and bank offline income to spend in planned chunks.
Whatever is causing your losses: treehouse survivability if you take damage, turret quality if waves clear too slowly. Exact upgrade costs are not public, so the page stays principle-based.
