This game to me, feels like a love story. you start out with nothing but a love for a special person. you collect some blues and yellows and get the courage to ask the love of your life to have a date, but then you het a red and she/he says no. you grow sad for a few days then collect a purple. you find out that he/she secretly likes you. you pass a few years and you two are together. every yellow you get is how much your heart is growing for each other hence the circle getting bigger, every time you get a red something bad happens, like having an argument or your love moving away from you, then you collect a purple and come to their house with chocolates, a rose, and a note saying I love you. you then either live with or without your love depending on how many reds or purples you get
