It was my mistake that I didn't do detailed instructions. There are no anomalies in the real world (so far). Pay attention only to other worlds
Are you supposed to be able to peek while holding the radio? Because i am unable to do so.
You need to find the frequency with music on the radio from 1 to 5 times. One of these 5 times there will be an anomaly in the door. You don't need to hold the radio when you're peek in keyhole
Ah that makes sense now, i thought you were supposed to check each number from 1-5 and check the door anomalies.
Written instructions may be required here to avoid confusion.
I will definitely make a more detailed instruction
