Definitely one of the most original and interesting takes on the theme. Unlike most other takes, this one actually makes me play the game in an entirely different way from a normal turn-based RPG. And it was quite fun and played out like a little puzzle game.Well done!
As for some stuff to improve, I think the game speed is too slow for the harder levels, and there was some cases where my unit was surrounded by two enemies, but rather than attacking one he walked into the attack of another one (who's attack was not blocked). This was unintuitive to me.
