I love your game! Make more! I love how many blocks there are for mines, way better than most other minesweeper games I've seen! You should make a theme or something for it :D like, tropical minesweeper! Or add a troll face as a mine and have an 'avoid the trolls' minesweeper! (yeah I'm looking at you Seth and Sumo! ¬_¬)
It gets a bit tedious once you've played it over more than once. 4/5, on account for the fact that the graphics were well drawn, and it was a well put-together game.
It's a good game, however I think it becomes tedious after a while. I doubt I could play the whole game in one go without being bored out of my mind. Great idea though. =]
