I have been ruminating about, but taking no action on, possible new features, and the one that keeps coming to mind is
(no, NOT a 'timed mode'. I hate timed modes) something like a 'pattern challenge' mode. Where instead of clearing
rectangles, you are given a simple pattern of colored tiles (shown down below the score) and the board is filled with
exactly what you need, and your challenge is to slide things around until you make that shape (imagine "red 4x6 in
middle of see of green")
So, NOT a sliding-tile jigsaw puzzle, but something sort of like that. Rules of sliding would be the same (slide entire
rows/columns).
I just can't decide if that would be fun or not.
