The Secret Lab is probably one of the better 'Medical Lab' style escape rooms that we've done, but with such a mundane theme, you really need to look to Passcode Escape to see how it can be done differently (if only slightly!) A lot of the trouble that these style rooms fall into is that they're over-propped. You have so many props and stylistic choices everywhere that it's so hard to figure out what is and isn't part of the game without putting weird stickers on everything. There were a couple times that we got VERY hung up on using a couple of the props when we realized that we were so off track from the actual puzzle. Intervention by the game master here would have been helpful, but I can understand why they don't always want to give it away. There is a very clear point in the room where everything changes. You learn something about the story, something happens and the puzzles flip on their head from this bland science mess to something much more....off the wall. It's such an exciting twist that really saves the room from mediocrity and propels it into something memorable.... .....But I wish there was more. Once you get past the initial twist, there isn't much else to do in the room before you escape. The final puzzle is another of those really exciting moments like in The Detective's Office where you can't believe you're actually doing what you're doing, and that it works that way, but Passcode just makes such good use of the space they have, you're happy it's there. Overall I'd recommend The Detective's Office over The Secret Lab, but they're both worth checking out, and keeping an eye on these great builders for what they do next.
