Monoliths Mario World II is a flash remake of Super Mario World for SNES that offers you 6 new challenging stages to beat. You can select any stage right at the start so if you don't like your first choice, you can always refresh (F5) and pick a new stage. I have to warn you now, the stages are long... very long in fact. There will be lots of puzzles to solve along the way as you traverse through overworld, underworld, and everything in between in your quest to complete each stage.
