Great, great sprite work. I'm a big fan of just having fun with character designs - so having a bunch of different character art (and dishes) was a big plus in my eyes, even when it doesn't add much mechanically.
As someone who is really dreadful at minesweeper I expected the gameplay loop to be torterous for me; I was pleasantly surprised when I beat it on my second run. Thanks for not making too punishing! Good choice in music aswell.
