i'm using firefox and the game works fine for me. i can't remember if you need to click for the game to start or just wait for it to appear.
Sorry i can't be of much help.
sorry, it's been awhile and i don't really remember...i was a bit sleep deprived when i was trying to get it to work, but i think clearing my cache was what did it in the end. idk how useful this is, but the game took about a minute to load before it worked for me. hopefully things work out for you!
