Hi all, I updated the game but sadly itch.io deleted all the save-data associated with the old build. I am very sorry, but I don't know how to avoid it. If you like the game I recommend playing the mobile versions which save the data. 

You can also use the official itch.io app. I just tested the game there and the progress seems to be saved. So if you don't want to play on mobile please use the itch.io app instead.

On the other hand, I will promise to not update the game for at least a month on itch.io to avoid any loss of progress.
