Challenges and solutions
-
It was challenging to get the right level of difficulty for my puzzle. I made many playtests to see how people were approching the puzzles.
-
I had to make it easier multiple times. Each time, it shortened the fast walkthrough to the point I had to create a new room close to the date of delivery. I added the third room and adjusted the fourth one to adapt to it.
