I’m not sure I did everything right. For starters, mention that “reset” is the top right key on the keyboard :)
I pasted the data, entered 300R and then it seemed to print empty lines for while, then returning to the prompt. R again this time seemed to run the game as expected. Is it right, you have 4 columns scrolling on the left side, with your character (Sir Colon) directable left/right. A bit further down a bit of code seemed to scroll by, and then I was suddenly killed by spaces :)
I’m not sure if I got everything right, so i refrain from voting.
