Did white resign?
At the end of the clip, It looks like Qc5+, not Qc5# as white would follow with Kh1. White still has the Rf1, Ne2 and the h2 that could give the king enough time to scurry. But it's very possible that I'm missing something.
I likely would have continued ... and likely got my ass handed to me. But there's always a chance the opponent will make a mistake.
