First of all, good job on the progress! Even though you have -as you mentioned earlier- just started programming, the game looks really good! As for the big issue you have got, I may have a solution:
I'm guessing you would use the numbers for percentages, which is a 1-100 scale. If you can spare a 5*5 pixel space, than visualizing the percentage by how much that space is filled in, it could be a possible solution (Like for 80%, you would fill 20/25 pixels.) For more precision, you could play around with the colour of those pixels or the size of the area.
Then again, I didn't test this, and I don't know the exact problem so it's just an idea ;)
PS.: For the borders, I think a dark-gray colour would fit better.
