I have built a post-compo version of Frozen Braid! This game version does not change the gameplay itself, but it adds the option to play by e-mail or over a chat program with file transfer or with carrier pigeons and thumb drives.

Here is how it works:

• Find a friend and agree who plays red and who plays green
• Select “start game” > “play by mail” > “create map”
• This will put a map file in the game directory. Mail the generated map to your friend
• Your friend must copy the map into his game folder
• Select “play by mail”>”make move”. Use the map and colors you agreed on. Your friend must do likewise
• This generates move files. Mail these files to each other
• Copy other move file into your game folder
• Select “play by mail” > “game outcome” with the map you played on
