There have been various discussions about this in the past, and all of them said that it was impossible at the time, but just yesterday (10/31/17) someone uploaded a TAS of the first stage of Shovel Knight Plague of Shadows (
https://www.youtube.com/watch?v=gVtZM74Y1jY). I am fairly sure that it is a TAS and not an RTA because of the extra bomb boost jump to get closer to the boss, which I am sure is very precise. Previously on Reddit and on TASVideos Forums people just said that it wasn't possible yet (

(no, I can't ask the creator of the video, because YouTube comments have not been working for me for a few weeks now.)
