Of the 80 Escape Rooms I have played, Birth and Time Machine were by far the best!
It started as soon as you entered the Escape Room, because of the atmosphere, Arthuro and the little puzzle, you were already in puzzle fever. The whole set-up with Dr. Mad (+Sonia ;)) and the background story was very coherent and I liked it very much, because you don't always see something like that.
The rooms themselves were beautifully designed, with lots of details and effects that you haven't seen before. The puzzles were also varied, imaginative and not too easy but also not too difficult. I also can't decide which of the two rooms I liked better, as they were both super good and ranked number 1 on my list of rooms so far!
For more of Dr Mad's future inventions, I will definitely come back to Milano!! :D
