At times these three worlds were just stupid. All you had to do was run and jump and you would make your way to the end of the level. However, there were also levels that were a hard, but not really hard. There are a couple places where the author tries to trap you. I liked the hard levels and thought the easy levels were pointless roadblocks. There was only one Bowser that made me think about how to beat him, but besides him, they were pretty easy. This level set could also use more scenery detail.
