Alekto
4 escape rooms
The clues mostly flow extremely well from item to item and room to room. It does have multiple rooms which makes for a more fun exploration element. But most importantly, it had interactive clues where you could actually engage with the props beyond simply decoding or unlocking. (And the methods of engagement were laid out clearly without being too simplistic.) Saying more than that would involve spoilers, but it adds a very engaging interactive element to the play.
Gameplay
Atmosphere
Very immersive, excellent design and effects, the bright lighting was unusual for an escape room generally but very appropriate for a laboratory setting.
Customer service
Does a great job providing nudges or hints at a level pre-determined (easy, intermediate, etc.)
