Hello! press space and type 1-30 to add some code to your code board (right). press d to delete some unwanted code! (choose any number from your code board, 1, 2, 3, 4 not the code you actually wrote) click x to play your game! and yes, it does not delete your code after a play-through. You can play your game as many times as you want, so its ok to spam x over, and over.
I made art, code, and all that :)
