It used to have unlimited saves years ago after the version 0.24 I think..
I stopped to read Password after that since I lost access to my newer saves after that and never had mood to manually renamed those all to back in the moment I last played it.
But It had only 2 lines per page, 6 slots. I have 150 saves anyway that long ago.
I probably need rename more than 100 files if I wanted back to have access to it all.
