It seems that holding an arrow key as a game ends and letting it go during the transition causes that arrow key to sometimes get stuck. I was at 2.8x multiplier when my up arrow got stuck and made it impossible to do anything else. I'm not sure if this is a browser thing or a problem with the game itself, but it stands to reason that any issues that make the game unwinnable should be weeded out. 1 star
Yeah I ran into the pig hunter glitch too. Whatever was supposed to activate and have the assasin take cover didn't work, so he just stood there until the game was restarted. Thankfully the glitch was early on in the game and wasn't that much of a hassle, so to anyone playing, don't let it discourage you from this really great game.
