How do I check if a save file alreay exists?

Hi,

The game I'm working on uses the 'save' and 'load' actions. On the title screen, how would I get the game to check if a save file already exists when a 'new game' option is selected?

It's not possible. When you save the game, you need to also write a key to Local Storage, for example "GameSaved=1".

Then you can read this key from LS to check if the game was saved.
