Needs to have a limit on how many people can be in a room. When we went they had over 14 people in a small room. After 30 minutes it was impossible to do anything because you couldn't move around anyone and avoid the zombie. There was a danger of someone jumping back from the zombie and knocking you into a prop.
There is no AC so it was terribly hot inside the small area. Some of the locks seems to not function well and there was a device needed for a clue that appeared to not be strong enough to do what it needed to do. There was a safety square on a desk you can stand on but no indication you could do that, but you got yelled at for standing on anything else.
Escape rooms with 8 people become very hard because there are just far too many communication lines. This had twice that.
Many of the puzzle and riddles of what you have already seen before. The real challenge deals with moving around a small space with a zombie, constant distractions from the guide who really doesn't help all that much, and trying to look at anything with a room stacked with people. You really need freedom to move for an escape room to work, and standing behind five people who are trying to distract the zombie while five other people are trying a puzzle isn't fun.
