Arrow Keys, see inside for sort of a tutorial. It will automatically save and load your progress and it won't mix up your data with other people's data, although I need a security feature so people can't mess with other people's data. Not secure, but works. I'll figure out security some other time.
Thanks to griffpatch for the encode decode tutorial. Rest by me. I used the power of lists to make this project. Also, it works, I just put a 2 second delay before it loads your data.
