Story Anon Sorry, I'm not sure where you'd prefer to see a bug report or if this is already known, but it's here. Just a little thing, when the perspective first swaps from the first to the second character, scrolling back to see a previous line sent me back to the very beginning of the game. You've noted that using skip generously seems to cause problems, but I had not used or interacted with the skip key before this.
The history button doesn't seem to work, from the normal UI it seems to do nothing, and from the right-click UI it brings up a blank history and the scrollbar can't be interacted with.
Additionally, visiting this blank history page and returning to the in-game menu seems to disable the return key and I become unable to return to the game, though the main menu button still works, and loading a save seems to fix this.
I didn't test before, but after this, the skip key no longer skipped seen-text, or perhaps seen-text was no longer registered as seen, I'm not sure and didn't test anything else.
Hope this is at least a little useful, good luck.
