I've seen and (I think I've) cracked the new code on the screen:
Dzimrmt, gsrh tznv xlmgzrmh xlmgvmg gszg hlnv kozbvih nzb urmw wvvkob wrhgfiyrmt, hzw, li sliirubrmt. Ru blf ziv hvmhrgrev gl wzip hfyqvxg nzggvi li hxzib rnztvib, R hfttvhg blf wlm'g kilxvvw zmb ufigsvi.
I used a subsitution cipher to deciper it and it says the following:
WARNING, THIS GAME CONTAINS CONTENT THAT SOME PLAYERS MAY FIND DEEPLY DISTURBING, SAD, OR HORRIFYING. IF YOU ARE SENSITIVE TO DARK SUBJECT MATTER OR SCARY IMAGERY, I SUGGEST YOU DON'T PROCEED ANY FURTHER.
It's a content warning of sorts I believe, and from a lore perspective probably has no meaning. It may be from Thomas Eastwood's brother (Isabella's Uncle) however I doubt it, and I think it's a fun code/easter egg for this itchio page.
