Changes
The issue with puzzle pieces stacking on top of each other has been completely and fundamentally resolved.
An autosave system has been implemented: - When exiting a puzzle, the position of all pieces (and more) is saved until the next time.
A Refresh/Reset/Shuffle function has been implemented: - Each start will have a new arrangement of scattered puzzle pieces.
Screen brightness adjustment has been added for each puzzle individually.
.The menu has been updated to reflect the new features.
And of course, numerous minor adjustments and optimizations.
