Great graphics - especially the title and portraits.
I felt that the grid space was too large, and also the movement was a touch too slow. it sort of felt treacly.
I wasn't sure about the keys - very odd. the space to pull things from the next tile was very counter intuitive. z and x for attack also didn't quite make sense - but I got it. A suggestion would be to highlight the keys when you first need to use them :)
On Safari the web build kept crashing. I thing that's more unity that you - lol
But great atmosphere and music all round :)
