The presentation of the game is quite strong! Your art is great, and the idea is neat.
I did not learn that the direction the icon on the dice is facing affects the direction the attack/arrow/spell is facing until I couldn't hit an enemy in level 4 for about 20 turns. It took another 20 to finally get an attack roll that faced the right direction. It might be helpful to align the dice to the cardinal directions after they finish rolling to better indicate which direction diagonals are actually facing, or to show where attacks go on the board to better show what's happening. There's some feedback improvements you could make for sure.
I found it quite difficult to use any manner of strategy either, especially once I gained and promptly lost a wizard: the fireball/iceball spells stuck around and filled my rolls with unusable options.
There's some cool potential here for sure, but I don't feel the dice roll system is currently intelligent/forgiving enough to keep the spark for me .
