Your game might not be loading for one of two reasons:
  A. The device you're using (mainly Chromebooks) are two weak to handle the game
  B. The school wifi (RSD Secure) is blocking network requests to games (smash carts[?])
If your game is just a white screen with it saying it can't get any info from a website, then it is broken and it needs to be fixed. Report it PLEASE.
ALSO ACER CHROMEBOOKS JUST HATE GAMES SO THEY LOCK UP :(
