You can lose if you get one of your resources to zero twice. I made it harder to lose because I did not want the player to lose.
But before I made some changes, it was very hard to finish the game, so I made it easier. Chances are, that you were just lucky, so the game was easy for you. But a lot of things are random, so you can lose just because of randomness, which can feel unfair to the player.
Originally I had planned on doing more with the "it is not real" theme, but as the submission date kept coming closer, I decided to include less of it, so all that remains is the child and a few more dialogues that mention it.
