Copy the "SAVE" folder that is in the "WWW" folder of the 0.10 build.
Paste that "SAVE" folder in the "WWW" folder of the 0.11 build. There shouldn't be a save folder in 0.11 build's folder, if you haven't played it yet.
Only works if you have a save in 0.10 in the first place. If you have started a game and saved in 0.11 you need to replace everything with the 0.10 save folder stuff.
