Yeah, I have to say that I didn't care for this. Its main fault is that it's too difficult. I mean, it has very loose controls. It would have made more sense to just have him move normally. It probably would have been just as hard to get all the medals. I liked hearing Luigi's yell.
This guy just flew around everywhere. It just didn't add up to much. I was kind of motivated. I mean, you had to work really hard just to get even the minimum score! Sorry, it just isn't for me.
