Last week I was with a man fishing. I asked him to teach me how to fish. Did he do that and did I learn successfully?

your colony dont have fishing. the man you meet was in a region it not a part of your colonye.
regions are a more Advanced part of the game and it demanding a bit of wepons and armor to take one it givs you bonuses. your foraging is rather weak. a roll a d4 dice on your behave and you have a natural -1 food so max you can get 3 food now per worker. you cant get hide from foraging.
you need the hunter cabin to get the hide. and hunter at your cabin gets 4 food and one hide.
the cabin it self cost 20 wood and 5 stone

btw you have Resived and steembasicincome share to day as a ty for playing my game.
