I made this a long time ago, but then I forgot about it. It might not work right on slower machines..or any machines.. who knows..
I recommend pressing F11 and turning off the lights.
it works, but its heavy as ... Godzilla... are you using sprites? why is the double gpu treading on? im getting 50-70% gpu/cpu resources ... not ok... u need to optimize that, it looked good though, even with high resources usage, still moves ok for me, so i seen whats going on:D
