The Days Of Christmas is a HTML5/WebGL game made in 18 hours for Ludum Dare 34. You click or tap lyrics close to the current line or verse as quickly as possible to maximize your score, but that's about it because it's unfinished.
The theme of growing in the classic Christmas song, the main verse grows as it loops over and over. As I type this, there are exactly 12 days until Christmas.
