The name explains it.
(By the way this was also a challenge for myself. I did not use the TAS editor to make this at all. All of this was made via save-states and real-time, with a bit of frame-advancing. Normally I just click on the TAS editor for the entire run, which is very painstaking.)
Also, if I get better at TASing this game, I will attempt a "No Going Into The Castle" TAS.(It is impossible to skip the castle theme in 8-1 and 8-3.
