Sorry, but I cannot start your game, I get the following error message :
uncaught exception: abort(). Build with -s ASSERTIONS=1 for more info.
Maybe because I'm in Firefox under Linux. But it's not the first game of a jam written with Unreal Engine that doesn't want to start. It's the first one compiled for the web that I notice, though.
I didn't rate it, of course. I don't want to drag your game down for that.
