Alex, can you test these and see which version is best for you?I'm playing on a 4k 50 inch monitor. The game displays remarkably well in general, nice work. However, the cursor is so small I'm frequently finding it hard to find. Often the best way is to move it off onto another monitor so the default windows cursor appears, so I have a clue where it will be when I move it back into the game window. Maybe an option to set a custom cursor or set its size somehow?
You have to rename the files to cursor.cur (remove the M or L) and place them one at a time in
(make sure to rename or make a backup of the current cursor.cur)
LMK if it makes it any better for you, and I'll see what I can do to add them to the game.
