That's cause you made it. New players will always have difficulty working your levels.
Look for my Pitch Black Jumping Challenge (Stupid I know), but look at the high scores. By leaps and bounds (and a shortcut that is in the level) I have the highest score. I only know of the short cut, because I made the level. Unless I show you where it is, you won't find it.
