I see some people are struggling on sorting categories, so here's a quick rundown. Glitched - You are allowed to use any glitches NMG - You cannot use any major glitches. Halt clip is a major glitch, therefore it is banned in this category. Glitchless runs also go in NMG. NG - You start off the run fresh with nothing. NG+ - You may prepare the game just the way you like before starting the run. (psst! if you enter the code in library when preparing and don't hit enter, you'll save time over inputting the code as all you have to do is hit enter!)
