This is cool! I really enjoyed the visuals and they definitely added to the overall experience of the game. Your background gif was cleverly chosen and your css styles also aided in storytelling. I really have a love-hate relationship with the snowing background. First, it makes the player feel very rushed and sets the atmosphere right. However, it also makes the text difficult to read, yet at the same time, perhaps it is this difficulty that makes your game have the effect it does!
