For a while, I played this game mostly on and off. Especially took long breaks around those annoying fetch quests (Finding lost items, finding 4 mimics) I also took long breaks because I had no idea how to increase my power and couldn't play the later missions. The game does a terrible job of telling you how to increase power. I didn't even know how to open my llamas until a week ago. I barely even TOUCHED the llama shop. A reason I stopped playing was because my schematics were terrible. The game NEVER told me about the store page in the llama shop. Another big reason I stopped playing was because I couldn't get any resources. The game NEVER taught me about expeditions, or at least it didn't make a big enough deal about it. It wasn't until recently that I learned about expeditions, research, survivor squads, upgrading survivors, upgrading schematics, and upgrading survivors. Games actually need to tell these players these things instead of just leaving them in a menu of endless buttons expecting them to find things on their own. About to head into the first Canney Valley storm shield.
