You should be able to either lose upgrades or discard them and choose different ones.  Right now there is no incentive to keep playing after you max everything.  I would like to be able to experiment with different upgrades without having to start over.

Maybe when you lose a guy you have a chance to lose an upgrade.

blood upgrades, wood, food and gold

Is it normal that bandits join to my army and follow my totem?

sometimes i can't pick up gold, not sure why

that gold is uncollectable

as you can see, my hand is covering the gold, if i take my hand away from the gold, it will still not collect

Just curious.

that should be awesome
