The only reason why I stumbled on this title is because I just found out that this title lifts an asset from this one.
Now for my opinion... both these Escape the Room titles can be brute forced and are both uninteresting, this one is just extra annoying step to deal with, which is forced to call the correct number TWICE.

Prerequisites. This is a modified flash file.
It is modified due to the non-deterministic loading thanks to the Newgrounds API.
You cannot nuke the internet, as that will result in a longer load in Ruffle comparatively to flash which loads the title instantly.

So how does one change things in order to sync?
Firstly you need JPEXS Free Flash Decompiler. After grabbing a clean version of the game only one thing need to be adjusted.
Change the contents within com.newgrounds.components -> APIConnector line 124 to just this:
this.loader.haltComplete = false;

Yes I just lifted this from One Chance.
Thanks for noticing.
