I found it and figured the importance of the sentence on the notebook. I was saerching withthe colors squares but it was in plain sight in one of the room.
Thank you for your help. I am continuing to try to find the exit of the escape room.
Yes. I'll be more spoilery for you here: If you've clicked the red square on the ground (near the entrance), make sure you have your notebook equipped and then you can look down at it. It'll turn green. Once you get off that screen, begin the sequence in the notebook. U, TR, whatever the order.
