i ran the game, and it said this : "Your browser does not support WebGL 1
Error reason: Web page caused context loss and was blocked. Try updating your browser and/or graphics card drivers.
Current renderer: (no GL: Web page caused context loss and was blocked)". I've played your games many times, with previous fuckerman games, but i've never encountered this while playing online.
P/S: sometimes it pops up like this : "Uncaught abort(). Build with -s ASSERTIONS=1 for more info."
