I wasn’t looking at all three signs. I didnt read the guide and was only reading room pages. The first room I couldn’t tell which walls were wet, I could only see the water on the floor. Second room I couldn’t hear any sound until i put the volume way up. Maybe it would have helped if I used headphones but I was on speakers. After that it was easy to tell the two signs, especially with the torch blowing, maybe thats a good first level mechanic as it’s way easier to tell apart :) Again these are very minor things, the game as a whole is pretty amazing and it’s impressive it was done in such short time period.
