Everyone who has at least once attempted to gather a soul from each of the 120 enemies in Aria of Sorrow, especially during a speedrun, knows the frustration it incurs after a hundredth failed attempt to get the required drop. Even TASers who were trying their hand at this category since 2006 had to put their progress on hiatus due to the amount of luck manipulation going on in nearly every room.
But all that only made the awaited result sweeter, as this first complete all-souls TAS beats the game on Hard mode in less than half an hour without even using glitch warps.
However, if you would like to see the game beaten to a pulp in a mere quarter of this time, don't miss the glitched TAS by klmz.
Note: while the movie doesn't use the glitch warps (neither by death nor by getting out-of-bounds using transform souls), it does use the normal warp rooms present in the castle. Starting from reset was necessary to take advantage of using Hard mode; it is normally not allowed — refer to the rules to see our reasons.
