Super Mario World Redone: Luigi Version

Super Mario World Redone is a hack that aims to create much nicer visuals for the original Super Mario World, while adding some new features, secrets and an all new encore mode!
The game also includes new custom music and lots of bugfixes for the original game.

As a bonus, there are four new levels for you to find, and they are very well hidden! Can you find them?

And in this version you spend the entire game with Luigi!
