You made me this game for our one month anniversary, and I had a great time whooping you (the picture proves this). The game brought me back to high school when we would play it every day in Chemistry, and then when we got bored we invented our own rules, like the one where you can put a piece in on any of the sides. I know that I don't really understand the code that went into it, but I am still really impressed, and I really appreciate the time you put into making it.
