Chrome on OSX blue screens, and so does Firefox on Win7... so it's not the browser. I did actually get to my game once, after deactivating ad blocker and clearing my cache, but it was a fluke; it hasn't worked since.
I keep glitching at the boss! The screen goes white and either the game freezes or gets stuck on flashing white nad never ends or the round doesn't even start right!
Please retry it now...
