New Features
Added note eraser: In note mode, press E to switch to erase mode. You can use Shift + Mouse Wheel to adjust the eraser size, and Right Click to erase notes.
Added difficulty selection:
In Normal Mode, after completing a certain number of tutorial stages, the corresponding rules will be shown directly as text.
In Hard Mode, tutorials will still require players to deduce the rules on their own.
Puzzle Fixes
Fixed duplicate boards — 2 duplicated puzzles were replaced with a new one.
Fixed all puzzles that previously had multiple valid solutions.
Changes
Removed all text-based riddles from the demo. These will appear only in the full version; the demo no longer includes encrypted text puzzles.
