This game, I am posting, is like Super mario Bros 2. Main character is Luigi as name of the post suggests. I think this game is very authentic and good actable. Luigi has bit greasy boots, but you can handle this. Music is also very good and aboriginal.
When you download the game, you have to unzip it and you can play. No installing is needed.
Controls are shown in the game.
In this game, you can jump when you take a mushroom and fire when you take a flower – this is classic mario approach, or classic luigi approach, if you want :-) . If you want to quit the game, you must press ESC-key and then you can quit.
I advise to play it !
