I just played through the current version. It was fun, even if the setting was a bit gruesome.
When I started playing, it took me a while to figure out I could click on the person in the other cell; I didn’t recognise it as the silhouette of a person at first.
In the “guess the ages of the children” puzzle, I got a bit annoyed that one of the clues was apparently “on the wall behind me”, but I couldn’t find a way to turn around; I actually rewound the game back to the previous section looking at the desk to see if there was a number on the wall I couldn’t remember. Turns out there wasn’t, and even if there had been a way to get that clue it wouldn’t have helped - it’s not necessary to solve the puzzle. I feel like it’s a distraction to mention it at all. On the other hand, I really liked the final clue - it was a great “But why would.. ohhh!” moment.
I used two hints on “guess the occupation” and one hint on “guess the number of the safe”, but I made it through.
