I'm curious, how does NG+ save a minute from regular Any%? Also, how do you know you have NG+ enabled? How do you turn it off?

If im not mistaken that category allows saves skips, theoretically if you load into an area and then quickly quit and reload your save it could put you somewhere different and/or closer to where you wanna be. Dont think this is actually possible but just as an example during the part with Lloyd you could get all the way to the key, reload your save and be loaded into the game at the front door (again you cant do that in this game but theoretically it could happen)

Actually there is a save skip w/ the train, If you leave the game while on the train and make a new game It does put you on the train once you enter the tunnel!
