Reviewing...
DrD2k9 has a made a really good effort in optimizing this movie. In comparing this to a human run, this movie is a lot more fun to watch..as human runs are just painful to experience.
In terms of optimization...I couldn't find one frame of improvement. There is only one frame lost and it was used to alter RNG. This adjustment provided a direct route to the last room, providing the fastest time to Senta. On the way, DrD2k9 also exploits a one frame trick that saves the most time throughout this run at frame 365. This prevent the "back-tracking" for Tomarc, so that he can start his accent jump much more quickly.
The only thing that I can not speak for, is how the game progresses in difficultly. This is a tough situation, where the pre-game "set-up" takes longer to configure; however, I figured the game should be played on the hardest difficulty...according to the rules
*If a game's second quest is just a harder difficulty mode, it is allowed by itself.
In comparing this situation, I have done two difference scenarios that have been accepted.
1.
#7232: nymx's C64 Boulder Dash in 11:56.00, which was played on the hardest difficulty and satisfies the rule above
2.
#6889: nymx's C64 Confuzion in 26:58.33, which was played from the very beginning and progressed until difficulty no longer increased (which completed a second loop of puzzles from 65 through 96...repeating the same puzzle from levels 33 through 64)
Aside from this one point, I see that optimization is right on, routing was perfect, and the goal for beating the game was met. In addition, the inputs sync for me and is good to go.
