I think the game use the browser cache to store your data, thus if somehow your computer crash, you lose the data.
if it can be stored in remote server it'll be cool, as we will then be able to play it on different computers using the same account.
is there any way to just save the downloaded flash for later use? so that I don't have to download it everytime I want to play, it takes like 10 minutes each time to download it...
