Not bad, but not good enough either
Basically a twist on minesweeper, as described, but:
Not very innovative.
The quality of the images is pretty bad, and the hexagons are small. If you stretch it everything looks even worse. Somehow the look of it is kind of "old" but not in a good "retro" way.
An the animations also look like a bad early 80s game.
Sorry, I bet you put a lot of work into this...
