Hey,
Does the timer start when pressing "Play Selected World" or when you start moving? Both Any% NMG & Glitchless do this differently.
Same with the ending, does the timer stop when the castle is exploded or when you press the lever?
Also, expressing my opinion that the category names are kinda bad cuz moving blocks is not a glitch, just an exploit.
It would make sense to have the time start on the first frame the game loads the world, so the loading screen at the start wouldn't be hardware dependent.
Anyway, timing the ending with the current ruleset, current Glitchless WR should be 20:42 instead of 20:32.
(Lever is pulled at 1412.146 seconds + 6.045 which seems to be the time that the two TNT takes time to blow up, timed by using other runs as reference) and the run started at 175.219 from Play Selected World or 175.916 from first frame loading the world, both leading to 20:42 (20:42.972 & 20:42.275).
