It's a nice twist on the Minesweeper formula. The hexagonal layout brings an extra level of thinking to the table, but those who are fans of the original minesweeper can settle right in without too many surprises. I found i was able to get straight into it, but found myself being quickly tripped up by old ways of thinking (which is good!).

My biggest critique is that for some reason you don't start off with the hexagonal format. I had to go to the Settings menu and switch from the standard mode to the new mode. The hexagonal feature is your game's biggest new feature, so burying it in the options can be confusing and put people off (anyone playing this is looking for a new flavour of minesweeper, so seeing the old flavour first makes you think there's nothing new here).

I like the themes. It keeps it as its own thing but allows you to switch to classic if you want to keep the old feel of it.
