1. Language Update: English language text has been rearranged and translated using ChatGPT. 2. Added cursor movement and control functionality: You can now use WASD to move the cursor and use "," and "." to simulate left and right clicks. 3. Changed the shortcuts for "about" and "dragging": "B" is now used instead of "A" to open the help, and "G" is used instead of "D" to control dragging. 4. Changed the judgment for squares with no numbers: Now, if there is a flag or question mark, squares with no numbers will still be opened, but the flag or question mark will not be removed. 5. Modification of scoring rules: Now when the AI judges that there is no calculation grid, you will not be punished for clicking the landmine, and the continuous scoring will not be interrupted (and the click will not be regarded as a mistake and added to the number of mistakes)
