I dont know what bugs you already knew off but the guy running around sometimes just appears at random and close lines you without you being to really react in any way. Some sort of tell to how the guy standing next to the mermaid is gonna kill you would be good since I walked right into him, walked away and then died a few seconds after.
The cleaning up sound was funny though as well as the rest of the noises. I like the atmosphere, the background music fits very well.
The audio tape you play at the begining can be played several times by just spamming e.
Cleaned up the place then left and won, something to tell you when you've cleaned everything would be good as well so people dont just wonder around for a while wondering what they should be doing next.
