I really like this, and if the price isn't too bad I'll pay to keep going as I've learn't more from this than when I've sat down to try to 'learn to do VIM'. I guess there's only so much you can cover in this sort of game format (I'm doubting there will be a .vimrc level), but if it goes far enough to teach me to take all the lag out of navigating and editing, I'll be a happy bunny.
