This is a good little survival story with creepy atmosphere and ambiance. I enjoyed each of the different survival locations and think the setting was appropriate. I was only able to find 2/4 endings, but sadly encountered a bug when getting to one of the endings.
The bug appears on the route where you have the noisemaker at the police station. Around line 469 of your script. I think it may have an issue that it called your sound that should play there "new33-3" It thinks that it should play a sound called "new33" instead. I suggest renaming the sound effect that plays there to a name that doesn't use a "-" as a quick fix.
If you update this I suggest maybe also adding the beginning narration in as text that shows up in the middle of the screen for accessibility sake.
