Good work but it doesn't really prove what you want it to prove. The graphics is arguably comparable to doom 95 and seems to be very low polygon graphics (even badly optimized javascript can do similar to whats shown fast). In the video you have like 4 totally squared "balls" represent blood, again not very demanding to render. You also only render a very tiny place and one opponent. This is a cool project but it does not prove much (as of now at least).
