This is is a non-lethal walktrough on hard difficulty. I will show how to go through the game keeping Lily safe while not traumatizing her with violence.
This is a game that combines puzzles, platforming and stealth in one game. Killing people will have an effect on Lily so I will play without killing anyone and we see how the game ends. Going non-lethal makes the game harder as you need to manipulate the guards to give a clear path for Lily to go through the sometimes complicated levels.
