This game doesn't want to work for me. It loads, then I get a screen with a "PLAY" button on it, after half a second I see a screen with three buttons: "STORY", "OPTIONS", and I forgot the third one. Then after two seconds the game starts. I can barely walk for a second when the "GAME OVER" screen pops up and the next level starts, but Mario doesn't even appear before the game starts going crazy and reloading the level every half a second.
I found the last shine (finally!). Oh, and there's a Spoiler: funny glitch (click to show/hide)glitch where if you take Luigi up to the final Bowser place (by using rocked Fludd in the same place as the entrance to "secret of the mushroom", you'll be able to do the course as Luigi (which is forbidden, when you enter the Endless Staircase you're not allowed in with the spell broken as Luigi). But, when you get to any of the cutscenes, it's Mario. So, you play as Luigi, get to bowser, and switch to Mario. Then you fight bowser as Luigi, BUT when you grab his tail it SWITCHES to Mario mid-fight. It's pretty funny to see happen.
