Changes in this update:
Now automatically saves when completing a level or changing settings
5-3: Now displays a small hint after staying in the level for 30 seconds
8-4: Reduced required waiting time
7-4: Reduced mouse movement speed
*Level numbers are in "row-column" format, in order from top to bottom and left to right, starting from 1.
For example, "3-6" is the 3rd row and 6th column on the level selection screen, independent of the level unlock order.
