Good tips!
Step1-Get 1 villager to fishing,have some trys.When He/She can fish go to step2 or keep trying!He/She can get food.
Step2-Get all the adult villager(not the one you teached fishing) to the reserch table.You might need to try more than 1 times.
Don’t forget the fire and the strange plants, you need it to keep your villagers healthy.
-If you are new to the game choose 1/2 speed.They will eat less food but the same work..
At the very beginning, I choose 2x speed until 3 of the oldest children grow up to 14 years old. And so, when I have only 2 kids, I go on ½ speed.
