Anomalies and the looping effect

Trying to teach myself to create an anomaly game similar to Exit 8 for my class project. Completely new to this so sorry if these are dumb questions. How would I do the looping map effect? I kinda have an idea on the anomalies but if anyone has any tips on that it would be great.

If you guys know any tutorials or stuff you could link me to that would be amazing.

Hello there @TamakiSoul7 !

There’s a guide on how to create an infinite hallway, in a similar style to P.T., the methods implemented here should be useful for creating something in the lines of Exit 8. Please check it out:
