I finally got around to playing SuperPhil32 World and got through about half of it. It is really well done. The levels are just the right length and difficulty for my tastes. There are usually alternate paths and lots of secrets to find. The boss battles are really clever, especially Kamek and Thwomp. Also, you can save your game and continue later on. I am going to try SuperMopitUp World once I am done with Phil's.
