glitch is a malfunction in N which often impedes the player's progress and can be quite annoying at times. For example, the ninja can go through oneway platforms, if they are placed on a corner. Many people, however, have used glitches to their own advantage in maps. For example, the maps Manipulate the drone, sir  by vrugtehagel and Lane Switcher 2 by w95559w are good examples of how glitches can be used.
