Latest announcement: Tournament registrations for Winter Worm Olympics 2012 have started! The Olympics will start on the evening of 21st of December :)
One of my favorite WxW maps that I used to have was a Mario sprite map with a layout like this: https://i.imgur.com/rlBcRwa.png , but it's not here on wmdb. If anyone happens to have that map, I would greatly appreciate it if you could upload it to Imgur or something. Thanks.
