I think it's a cool game (if a bit overly long without rests/breaks/ups and downs in terms of pacing; I got more bored than I was challenged after a while) but I'm not sure it's particularly related to mahou shoujo other than the ship being a girl who is magic. i think you made all the pre-made assets work together really well (I particularly liked watching the background scroll; I know making a looping background can be suprisingly annoying!)
