This is such an original use of ChoiceScript! Wonderful, creative, strong writing. It's incredible how much interactivity and freedom to experiment you packed into 1000 words.
Based on what you wrote in the description, it sounds like the game originally had all of Alex's dialogue, and the 'parser error' was introduced to cut it down to fit the word limit? I understand the way that represents the communication gap between human and machine, and it increases the challenge of the game. But it also makes it difficult to get a sense of Alex's character or fully follow the plot. I wonder if you would be willing to do an expanded release after the game jam? I would love to play a full / longer version of this.
