Press the green flag to start, and from there just try to click the heart. If you can't hit it every time, that's okay! There isn't really an end to this, so it's just a time waster.
I will update this for other holidays, and if you don't celebrate Christmas, I'm sorry that I didn't use your winter holiday. It is what I celebrate, so that's what I themed the heart candy after. I am not going to force you to celebrate this holiday, so go back if you want to.
