I remade the game using the Zinc compiler! Which, unfortunately, could not find anything other than the trial version! But the functions that are there are enough! Moreover, to my surprise, Steam functions started working (overlay, screenshots, etc.)

But I don’t recommend opening the Overlay - for some reason it slows down, freezes and has difficulty getting back into the game!

However, now Flash Player is not required - the game will open on any PC!
