I like it.
I did however not realise at first you were meant to read the book each time a new error occured. In my first couple runs I was trying to memorize the difficult to memorize rules. But when I realised I was playing it wrong it got much more fun. The way I would force players to not memorize the book and to add replayability is by making the rules in the book slightly randomized.
I really liked how you didn't know how much time you had for an error and how you quickly close your book to check the lights, the gameplay loop is pretty fun.
The artstyle is also clean and consistent. Well done. I especially like those notes in the background
