Making the screen go all black (from all black with a tiny little gear in the corner for half a second) as if it's stuck loading is a really trolly way to tell people the game is ready! Kinda funny, but definitely frustrating.
I mean, come on, I'm a newsground user on the adult section, you can't expect me to figure out complicated stuff like a left click on a blank screen on my own. It took me almost 15 minutes.
