It could be useful if it does not create a new buffer if the one we are in is empty. For instance, I just changed the beginning of the HJKL() function to be
414 function! s:HJKL(...) 415 416 if bufname("%") != '' 417 "create new window for game 418 new 419 resize 100 420 endif
Bug: Exits Vim
After the game has been won, or when 'q' is pressed, the current Vim window closes. If only one window exists, however, it exits Vim completely, thus requiring the user to create a new window beforehand (and set it to max height, or the game returns a message that it needs more room). This is true of both Vim and gVim. The user is not notified as it says "type q to quit the game". You might want to fix this.
--- I agree, it's a great way to get those controls into your muscle memory but the fact that vim exits after every game makes it kind of annoying. I'd love for it to continue with the next game. I can always quit it with q.
