Very buggy game, and not entertaining.
Sorry to say this dude, but there are a ton of bugs in ur game and you should of fixed them before you submitted this. For example, sometimes the luigi sprite gets stuck and not able to go through a certain path, and I also died when I hit one of boos turned into a star, and he was still a star when it showed the death pause thing. It was a cool idea, but the music also pulled down the experience, it didn't seem right for the game... Don't give up, ur almost there, just ask ur friends and make sure it is fun before you submit something. Hope that will help you improve ur skill, and technique.
