It's karaoke time! But, why do these halls seem to be looping..?

After attempting to fix stuff at HQ, you bike just around the corner to a quaint karaoke place to de-stress. The Doorwoman hands you the key to your assigned karaoke room: Lounge 503. You start heading there, though, something seems to be off about the hallways leading there.

INSTRUCTIONS:
- After Hall 0, some things may seem to be out of place. Those are anomalies.
- A hall can have an anomaly, or none at all.
- If there's an anomaly, return back. If there's none, continue forward.
- Hall 0 has no anomalies. Take it as a reference hall.
- The halls/anomalies are randomized, so every run is a unique run. Good luck, speedrunners!
