Can you escape from this loop?

The setting is a school. The protagonist returns after hours to retrieve something they forgot, only to find the school engulfed in an eerie silence. On the way to the classroom, a strange feeling of something being off strikes them.

Before they know it, they are trapped in a strange hallway with no way out.

A note is posted along the hallway.
“If there’s something strange, go left. If not, go right.”
Could this be the rule of this mysterious corridor?

No matter how many times you walk through, the scenery remains the same.
Can you spot the recurring anomalies and make the right choices to escape from the hallway?

There are a total of 34 anomalies. Can you find them all?
