In June 2019 I started another TAS of Boshy under the main RTA category (any%, Average-mode, no Wrong Warp, Dark Boshy only). In 2013, when xwidghet created his 30:37 TAS, large timesaves such as Double Shot technique and World 4 skip hadn't yet been found. A year later, MopeyJo released
his 26:45 TAS, where he inluded these timesaves. However, looking at this run, there are many places where it could be optimized even more.
Almost every boss can be done faster. For example, Stonk, a real time speedrunner,
managed to beat Hello Kitty boss one cycle faster than MopeyJo's TAS. Besides that, there are many platforming timesaves. The major one is
Kracko Skip, which I found in the progress of my TAS. That jump was known to be possible only with Sonic, the inputs to do it with Dark Boshy are extremely precise and unobvious. It saves about 50 seconds of a long miniboss fight as well as one platforming screen.
As of right now, I finished World 6 at 10m 4s, which is almost two and a half minutes ahead of MopeyJo. I hope to finish my TAS in the future and submit it to TASVideos.
