|Level Start Frame Jump
The Level Start Frame Jump is an advanced trick used in Super Mario Maker. This trick can only be done on levels that start from a fall.
How It Works
Mario stays on the starting platform for 2 frames before he falls. Pressing jump during this time will allow Mario to jump instead of falling.
While this is normally a 2 frame jump, it is possible to make it a 1 frame jump by placing a falling platform underneath Mario.
By holding down before the level begins, Mario will immediately start ducking as the level begins. This allows him to perform a duck jump on the 2nd frame.
