This was a short, well-written game about a horrifying experience being trapped in the darkness.
Most of the game is about your reaction to the things happening to you. The hardest part is the fact that everything is in complete darkness, making you have to react to everything without knowledge of what you’re truly experiencing.
It stays mysterious to the end. I did make a silly translation mistake in my head; when the game says you are surrounded by (Spoiler - click to show)miles de patas, I accidentally thought it said (Spoiler - click to show)miles de patos, and pictured the lights going on, revealing that your enemy was thousands of ducks. I laughed and thought that was fun, then later realized my mistake. The actual story was quite grim, and had a fitting ending
