Ooh, that's good! At the risk of being spoilery, the pacing at the start was a good introduction, then when things opened up and it became about solving a mystery, it really sucked me in! I fell hook, line and sinker for the red herring, so when things started getting weird and things became revealed, I really enjoyed it.
Also really enjoyed having to react to the blackouts. It made for interesting choices, like when I could have taken a gun. Most games, I would take it, because it's there, but I had just burnt some documents because I had a lighter, so as I thought "Probs best not to take the weapon."
Only real criticism is when you start detecting, you're given a massive list of choices. There's no real issue, but it does feel over whelming, especially because there's no real place for you to go at first. Maybe spilting rooms into floors, would make me feel a bit more "in the world", and would make the choices a bit less overwhelming.
Really enjoyed this!
