Story mode is the primary game in which players work towards the ending target. Practice mode is helpful for those becoming used to the game. The police officer that is usually pursuing you is preoccupied in this mode, so it is a little less tense and lets you get used to the commands and abilities of your character. Never-Ending places you through arbitrary amounts; as it'll keep creating another arbitrary amount until you leave into an alternate way, you are never actually ended in this mode. There is also a multiplayer mode that lets up to four players to quadruple your interesting!
