Would suggest a mechnics/controls change. Instead of choosing the (out of context) next action via the top/right bottoms, better highlight the area per default after each step (without pressing additional buttons). This would make playing the game so much more straight foreward.
Players then can easily see where they can go and if they can attack any of the enemies.
It's almost everything already there, only a different kind of highlighting for attack tiles would need to be added.
