The problem I've got is that you can accidentally overwrite any text that you are given and get stuck with no means of getting the original text back. I clicked and it deleted the 'hidden' text and I could not get it back.
And later on, something broke and enter key stopped entering commands but simply selected them, making it impossible for me to input the final command :(
Soooo, long story short had to replay the whole thing and it was a fun little experience!
