I loved the artwork and the writing. They give the game a lot of charm. You nailed the theme too!
Unfortunately, it took me a few attempts to understand what I needed to do and once I did, it felt a little tedious.
I think it would help if the correct answer was an option at the start and only required you searching for it if you didn't already know the answer. I also found it tricky that the frozen time mechanic would automatically stop when I tried to walk past the desk. This meant I had to take the long way around sometimes.
I think a couple of gameplay tweaks would make a huge difference because the presentation and artwork are already great!
