1. Here the problem was that my code wasnt that good so when creating a new bulding and  all placed buildings were in different scripts and I I figured  changing things in the 2 most important files would not be a great thing to do in the last 10 minutes.

2. Yeah I get that point with the white text

3. I did not even thought about statistics good point 

4. I know I could just listend for any key press to move on or created a button but I was in a rush to make this big game in this little time

5. Yeah a castle houses 750 People but they also make money in a lot of ways probably trading, black smithing and making other goods, In real life castles have a lot of utilites and so I figured I want to mimic this in the game.

The Food Display :  

I currently have 6040 Food. The Number in the brackets is the total amount of food I will get or lose everyday the calculation for the total  amount of food per day is 

(Amount of Food Created by all Buildings) - 2 * Population.  // People eat 2 ''food' per day

So to anwser your question. X is the amount of food your currently having , and y is the total amount you gain or lose per day.

Btw have you seen the You ran out of food screen ?
