Very good game overall, but a bit too simple. Very original and correctly respects the "one" with only one button to play.
However, the attack phase both lacks clarity and impact on the gameplay.
The presence of the settings menu is a really good point, indicating of the polish of the game, that far too few games have.
Really Good game overall, even though it is too simple, and need a clearer way to convey its intentions to the player.
