Game utilizes a really interesting control scheme that is a challenge at first, but as you play more you get used to it pretty fast. I liked that the player actually moves and not "snaps" to the grid you click on, this lets you do diagonal movement. Also I loved the artstyle, the SFX were also fitting.
As for improvements, I really can't think of many but, perhaps, maybe in later levels add more "boards" so you have to control more than one character at the same time - this would also fit more into the theme. All in all - enjoyable.
