Tried playing and it runs pretty bad on browser with dropped frames at almost every movement. Cool idea though and I haven't tried the multiplayer version but if that works then 3 days to get that working is really impressive!
Sad to learn it, when I checked the rendering the profiler after optimizations it was giving me ~1ms per frame, so around 800 fps. But i have done some polishing after that. I rechecked and it is indeed much more heavy now, I will provide an optimized version.
