SSNC
My uncle just tried ULTRAKILL, and I found it annoying when I realised I couldnt name his save, so I made this mod.[check the githubs readme https://github.com/Bryan-000/SSNC]
heres some tips for when ur using SSNC: To change the names of your save slots, click the name of it and start typing. You can toggle between 2 types of UI in the config.
