Are there any further issues that need to be addressed with this before it can be published?
Its boards are having the same problems as in your other game. They are too large, and when they resize to fit the screen, the rank and file markers are too small. Perhaps you have a 4k monitor, but I have an HD monitor, and I expect HD monitors are still more common. On an HD monitor, the maximum screen height is 1080 pixels, and a height of 3025 pixels is overkill. Actually, it's overkill even in 4k, since its maximum height is 2160 in landscape. But if you have a 4k monitor in a portrait orientation, you could view a whole board image without resizing it.
