Trap, conspiracy, cold machine, switch, key, rise ladder. I hope that I am you, to get rid of this nightmare-like lost city. I am Lilith, my memory is locked. When I woke up, I found everything to be so bad.There is only a little memory left, my brother is my only family, but I can't find him now.Only one robot stay with me, Suffered endless torment.Please don't care about these thorns and lasers, please don't be afraid of these punching machines and monsters, because what is really worthy of fear is the endless despair.Is my memory really locked in these iron blocks, in wooden boxes, in mystery?Why is this robot like an enemy and a friend,follow like a shadow? I hope you can enter my world, help me find lost memories, find the truth of this laboratory, and find the lost light. I want to know in the end, my despair, it is broken by you, or to pass on to you ...
