I loved every second of it, the atmosphere was incredibly well built and the puzzle were short and quick enough to retry not to become too much of a chore even when I got stuck on one (the ERROR one took me a few tries to understand the correct order of operation, as did the 4 coloured buttons). In a way the puzzles reminded me of Keep Talking and Nobody Explodes, except without a manual reader to help me through the solving process :-D
