I love a good mystery in Interactive Fiction, and I was excited to see how this one would play out.
There a lot of ways to do mystery in IF: have the mystery play out linearly or as a results of puzzles (so the gameplay doesn't involve the actual mystery); hunting for specific clues; and actual deductions by either the player or the character.
All versions can be made into very engaging games. This game does pretty well, but it didn't quite reach the level of pure satisfaction.
This game, according to the author, is "a small project I made to learn Twine and experiment with Interactive Fiction in general", and it's much better made than many other first efforts.
Story-wise, it's a cyberpunk mystery where you have to search people's memories (or engrams) on the 'net. Gameplay-wise, you're hunting for a motive, means, and murderer.
