Sorry about this! You should be able to right-click to go to the previous scenes as well.
I'll add in an update ASAP to have a UI back button on those scenes just to make it easier.
Hmm. Not sure if I tried right-clicking.
If you can, add a UI back button to the journal books, too. I am able to back out of those by hitting backspace while my photo album's open, but I figure that's not one of the game's puzzles ;)
