Hey there, me again.
I recently got myself a new computer with a 4K display, and this game shows a few problems when subject to a higher resolution.
The text in the Statistics window is extremely small.
The cards in the Card Game also appear to be extremely small.
Since only a few UI pieces are screwed, it's most likely caused by some code you wrote altering the size of the UI and not taking into consideration screen size.
It shouldn't take too long to hunt it down and make a quick fix.
I might've missed something, so It'll probably be a good idea to have a quick look over everything and make sure everything else is fine.
