I only use one VM Just for this.

MURDER is a 2014 Flash game developed by Studio Seufz, who are based in Stuttgart, Germany. You start the game as an assassin plotting to kill the king. Your goal is to sneak up behind the king and quietly take him out without being noticed. While you're following the king, you must charge yourself up to stab the king by holding down the space bar; if you manage to fill the bar up completely, you kill the king and get to take his place, but if the king sees you the game is lost and you have to start over. Make sure to stop holding the space bar when the blackie looks back to avoid being noticed.

There's not much info I can manipulation in Ruffle so I only can do is aim for fastest completion.

To remove Preloader, You need JPEXS Free Flash Decompiler

Go to Sprite

Find DefineSpirte (1155) And remove frame 1

And now save it.

There's not much programmer and tools in TASVideo, That's why they're afraid to ask.
Also TAS Flash game are exclusive from Linux
If they truly hope this, they will contribute to Ruffle, Implement what they want.

feos: Claiming for judging.

feos: Replacing the movie with a version that starts the game sooner due to removed loader.

Tried this on both removal methods:

sprites -> DefineSpirte (1155) -> frame 1

and

scripts -> frame 1 -> PlaceObject2 (1134: APIConnector) (:APIConnector) Depth: 148 (ads)

and the first frame to hit Play doesn't change, so both methods sync fine.

Original game (loader causes non-deterministic game start):

Also accepting while I'm at it, because it looks well done.
