This is incredibly visually stunning and a very creative take on the theme. I like this submission a lot! One thing that i think i would change about it is the camera angles, once you get onto the tower is very hard to get your character moving exactly where you want them to using a 4 directional input like WASD/Arrow Keys. I think the game would feel a little better if you were looking at your character with such a weird angle, or if the game was being played on a joystick.
Still though, great submission!
