A lot of bottlenecking. Would be pretty miserable for large groups. Also several elements were either broken or not working particularly well, in a way that left us questioning whether we had figured it out. We had to use the hint button much more often than we usually would, and the game masters were not responsive.
We seemed to be passed through three different Game Masters. Hints were clearly automated and in no way related to what we needed in a given moment: for instance, at one moment, we knew the safe code but it wasn’t opening due to an issue with the buttons. We asked to confirm the safe code, and the auto-generated hints on the screen kept displaying steps we had already completed. Other moments, the Game Masters failed to trigger things that clearly they had to manually trigger. Overall, they seemed distracted, and it really hurt the experience.
Another team we spoke to also mentioned having issues with irrelevant, outdated hints.
