Defend the Tower! click and hold to pick up resources Resources are limited so build mines and farms hover over the bottom to select buildings click on buildings to place them some buildings like the mine and forest produce materials over time double click on certain building to upgrade them (10 stone) then (15 metal) space to shoot at Zombies! don't run out of arrows
i recommend getting a tower and workshop up first(makes arrows) then waiting until you can building other structures
