How to get more stars?

I read the instructions about how to play June’s Journey before I ever started playing the game. When the game first opens, close to the upper right hand corner of the screen, there’s a gear inside a small green circle. Tapping on it opens the menu for “Settings”. Under the “Basic” heading is a long green bar labeled “Help”. Tapping it opens a list of topics that provide fairly detailed (but not complicated) instructions and explanations about how to play the game. Anyone reading all that’s listed won’t have too many questions after.
