I know how it works, and i read the guide, but further in the game, your -(number) goes down. For no reason. None of my agents are dying, and i don't know why this suddenly happens. May someone help?
Sorry it took me so long to notice your question. I'm guessing you mean the danger rate? There are various things that can affect it, and not all of them are explicit on purpose. It is meant to be discovered. That said, I understand it is confusing, and can lead to sudden game-over. I'm thinking about modifying the way it works to avoid that problem.
Most likely you didn't have enough power to stop some event, or if you left it alone for a long time, enough agents died and were replaced that their power dropped (every time an agent dies, you lose a little bit more ability to fight than that agent was worth). Can you send me your save file? They are automatically backed up when you lose, and there's a button in the pause menu to open where saved files are located.
