Linear, yet needed 4 people minimum (only needed 4 people for one of the puzzles) and was very claustrophobic throughout with just 5 people. Puzzles were kind of a stretch, and not like typical logic based puzzles in escape rooms. Not enough for everyone to do for sure. I think total there were only 7 puzzles, one of which was auditory, with a voice changer, and no subtitles. While figuring out (correctly) where to place the last object, we were told (mocked, really) that if we had listened to the recording, we would have been told how to get back to where we needed to place it. After the game we were told that the owner intentionally designed the game to be difficult, not by making interesting and complex puzzles, but by making a stressful, cramped, overstimulating and uncomfortable environment. I will say the rooms *looked nice, but it almost made the puzzles that much more disappointing. There was even a key, that was just a red herring! Ridiculous.
