It's rather big but it has to be because of all the small details in the KS pixel art. By the way, if I've used images from your level and you object, please tell me so, I'm sure we can work something out! I've also credited all the levels used in this wallpaper (I don't think I've forgotten one, but if I have, I can easily add one more credit) so you don't have to worry about that
@Aptequar: Where did you get your wallpaper from? It looks amazing!
