For some reason, the screen is too big for my monitor and there seems to be no way to shrink it down

I am sorry this happened. I somehow expected that everybody has 1920x1080 monitors, and everywhere set such resolution, maybe thats the case? I changed some embed option for my page (set it click to launch in fullscreen instead of embedded and enabled scrollbars). If you have time, please try again and say me whether it works or not this time.
Edit: if your resolution does not allow you to go into full screen without game screen being cut, maybe you also need to mess with zoom of game page outside of the game itself (while not being full screen game is fully playable now, just too big).
