Hm, I am not so happy with the game at all. I spent a good hour or so for it and played a little around.
To leave the good points aside i dislike that I have to kill over and over again the same enemies when I come back to a screen and that is a pain. Another point is how your character stands on a ladder. You can stand easily by the side of a ladder and you don't fell down. This is very obvious and imho a lack of quality.
But when you get over this it seems to be a good game, but I am not in it right now.
