Nightmare Loop is a small video game. I present a feeling form people live in a very polluted area by creating “a sense of urgency” and “a feeling of hopelessness”. At the beginning of the game, monsters will surround you in all directions, and you can choose to resist or to avoid their attack. However, at the end of the game, you will face two options, ‘kill yourself’ or ‘be killed’,then you wake up from a dream and discover that the new day is waiting for you again, never end.
