jQuery is... a bit on the odd side, I'll admit. It calls itself a library, but its behavior can act more like a framework!
As for the bugs, the tutorial regularly softlocked due to the button to continue being missing (I notice the text is moving off the thing, which might be part of it).
CrazyGames *is* effecting it, as they've disabled the fullscreen function and are pushing many ads that are starting to interfere with the game itself! If you were to pull up a network view and see all of the CG stuff that is being loaded alongside the game.
I would also appreciate it if you could elaborate on the publishing agreement, as you've not done so in any replies yet
