Positives:
The styling is excellent. Without even reading anything, it's an obvious sci-fi setting and the font and colors work very well in conveying that.
I also so the memory puzzle addition. I would not have thought of adding that sort of challenge into a Twine game and that is very creative, though I did have one problem.
Negatives:
It could have just been me, but I could not get the good ending because of the puzzle. I wrote it down every time and checked back at the phone for more tasks, but I just could not get it to work.
Another thing I could say if I was being picky was that some of text seems long? With the context of being in a rush, the intro and some bits feel a little much to read through in one big text block. Again, I'm just being picky there and I actually quite enjoy the writing style!
