This game was released on android at a point (and removed from the store later). It's my favorite game ever.

  This is a cross between Minesweeper and an RPG.

  You gain levels by killing weak monsters and win when you defeat them all.

  It's a bit different than Minesweeper in that the number you reveal when you click on a square is the total of the levels of the monsters in adjacent squares.

  When you click on a tile with a monster in it, a battle begins.

  First you attack, and deal damage (equal to your level) to the monster. On the next turn, if the monster is still alive, it attacks you back. Your attacks alternate until one of you dies. You don't see this, though -- the battle plays out instantly after you click.
