I played the game to the end. Apart from the janky character animations and weird pathfinding, it's decently made for such a small team. However, in its totality, all the suffering the main character (or all characters?) have to go through feels pointless. There's no catharsis, and I couldn't find a deeper meaning (maybe there is for you). Many of the puzzles' difficulties come down to having missed something, like an item somewhere that wasn't obvious, or using the right interaction at the right spot. The game doesn't give you feedback on why an action is not correct. Much of the story exposure is done via endless texts on PDAs and computers. While I'm not adversed to reading in games, it felt mostly tedious, but necessary to understand the plot. I can tell a lot of blood, sweat, and tears went into this game, but I can't really recommend it over better point and click adventures or other horror games.
Loved it and I hope they'll make more like this. If you liked the original Gabriel Knight adventure's atmosphere, you'll enjoy this one too. The puzzles aren't very hard and you make progress easily. So if you're in it for brain teasers, it might be disappointing. I really liked that it was light on puzzles and heavy on mood and story.
