I've been looking into learning vim motions (after using vim for nearly 2 years; I know, I know. I was using arrows before that, I'm an idiot), and this game will be very helpful in my process of learning vim motions.
I am still using the arrow keys, I must be an idiot , too. If this script helps you with the vim movements, you can check out for the same reason two or three scripts of mine, in the same repo: tui-mines, mneme,tui-sudoku.
