For the quote that you replied to, when you reach the next level you get a pop-up and it tells you what you get. When you master, you'll get the second popup giving you a gnome. Also, since this was posted, TL changed Level 4 so that instead of the coins you get one gem.
For some of the other information, such as how many crops or trees you need to get to each level, I counted it.
I am ****. I have a spreadsheet of all the information I've collected for FS, RS, and BS.
