Hey thanks for checking it out!
Agreed we had an updated letter removing that mention as we decided to remove the hunger bar last minute in place of a vignette to try show the hunger but didn't get a chance to update the letter. The noises ended up being randomly generated to save on time, in the future, we're aiming to have it get louder/react to specific letters etc. And good point, we hadn't thought of that, we'll have to make a note of it as we definitely plan to add more floors, days and levels.
Thank you so much for your feedback!
