Up arrow is + Down arrow is - left arrow is delete right arrow is enter
I saw the project and thought it was cool, but there were a few bugs I decided to fix. I might add a few things, but for the most part I just wanted to fix the problem with it being almost impossible to type. It's cool and it would have been nice to see it further developed. And tankist-scratch, if you see this, just use scratches built in text inputs. it's infinitely easier and you get full access to the entire keyboard, instead of just the valid input buttons.
