Hey,
really nice and well polished game you got there. The Art and Style are very coherent and fitting. The idea was pretty neat incl the ideas for the changes and it took me a little to beat, but meanly because of the fight at the end (I am not shure if it was necessary to beat it, but I did not wanted to take any chances. :D) There is also my only critic. The fight was not so cool with all the running and this also showed some flaws in the movement with the queueing and snappiness. You would not always stop, when releasing the button but move one more tile, which was annoying during the fight. The length was on the edge for me. As I was killed the first time at the end. And I needed to do it all over after solving it. (Also there was a bug for me, after I got killed I could not leave the room. I needed to restart the game.)
Great entry. Very good work!
