The Live Leaderboard is now online. You can see it below the game. Currently it shows any registered member that reached a new wave within the last 15 minutes. The leaderboard auto-refreshes itself every minute. If you change your avatar, the new one won't show up until you are offline and come back online. So that means you need to stop playing for over 15 minutes. We did this caching for performance reasons. Let us know if you have any questions or requests!
