Not much, just move your mouse, press the snowflakes on the snowman to hear a "pop" noise and they will "melt" Wait a minute, and there will be a change in setting Turn on the sound if you want, its music and "pop" sounds
I was bored.. Sound is Canon in D Major! Thanks to @FierceDragon for telling me Its a continuous game, so pop and watch the day change however long you like
