This update addresses a few bits of feedback:
[list]
[*] Added edge scrolling as an optional setting.
[*] Added a brightness slider for the highlight around the cursor.
[*] Added recovery mode which can help recover some progress in the event of a lost save.
[*] Fixed a bug that would allow the undo button to clear tiles from a solved region (any regions affected by this will now be fixed on startup).
[*] Fixed an issue with clue numbers temporarily disappearing after solving a region.
[*] The top-right global counter is now also using the clearer font.
