Hey! I've create a little tool to share easly the different link of your game. All the information are store into the URL. You can add link to Itchio, Newgrounds, Gamejolt, Steam, Armor Games, Google Play, App Store, Github and Ludum Dare. When you add a link to Ludum Dare, you can enable a banner on the top of the page to display the game are made for the LDJam.

When it's finish, you just have to generate a link at the bottom of the page and share this link!
