Thanks for playing the game!
So far there are no multi-loop endings - each loop is standalone. In a subsequent update I did add an achievements list to help track what endings or secrets you've seen between loops but that is as far as it goes into terms of what multi-loop completions will change. And the diaries and notes are just there to provide some lore/flavor text to the game. But after reading your comment, I may reconsider things; it could be fun to have a more complex ending involving multiple loops or secret optional interactions 🤔.
Also, is there something in the desktop at the right of Kronii's room?
There is indeed a secret there! But it is a little harder to find since I forgot to leave any subtle hints for it so to find it will involve finding that random pixel on the screen.
