Looks like I am too late but attached is a save and load demo. You only really get two options with save/load, a string or an array of numbers. What you want to do is save and load the state of the player and game world. For instance what do you have in your inventory, have you found the secret door in room 27, etc. It doesn't have saving and loading, but my text adventure game is: BDWE58AV
