occasionally my character will start moving in a direction until the reach an edge, and I cannot make them move other than to stab or make the other animation, and I have to reset the page, because even if the char dies, usually it will not accept the c as input, or the char will immediately be stuck in one place upon respawning.

This seems to maybe not be happening any more though. Maybe you fixed it? Or maybe it was just due to traffic.

Also, the highest score I've gotten is 22, though that streak started with only 6 other players (and ended with 10 or 12).
