Love it , a clever reinvention of old-school sweeper, i also like the fact that numbers in cells decrement as you explore further , keep it up. (wonder if you could develop this design even further and put a price tag on it)
I want to point out a few things, sometimes numbers on the border lines are displayed incorrectly or is it intended? For example in this screenshot the most top-left number is '5' whereas there is only 1 cell that is empty around it.
And one more thing, I like the color pallet but it would be cool if the numbers would be colored according to their rank: 1 is blue, 2 is purple, 3 is pink, 4 is orange and so on, like in old sweeper. It appears kind strange to see the same '2' number colored different colors.
(nevermind, forget what i said about the colors, now i get why you did it like that, this is intended, you are a clever guy what can i say)
Thanks for the experience ;)
