Just keep on building buildings @librarian
If you buy any buildings, buy only the 3 most expensive you started out with.
Then you will be able to upgrade the rest on your production.
When you in the future start to train soldiers. You save your weapon and alcohol production up to your safe limit and by soldiers for everything. That way you will start out with an army that is bigger and maybe they can not wipe you out. If they do wipe you out, give us all information about what is going on. Then we will make the attacker leave you alone. We are here for the whole gang.
In the gif you see one of @Barbro 's cats training to be a real killercat.
