Make the game know when it's over

Is there anyway (I know there is) that after the health bar goes to 0 or negative that the match immediately goes to the next round?

Also when that round is over is there a way for the game to do something similar to what Mortal Kombat did with the Finish Him/Her type of thing and then have a time limit and wait for the player to hit the person or do an execution?

Yup- open level node

the same or new

Is that it?

What do you mean by the same or new

Yeah, reopen current level or open new level

if it simple as death counter, reset stats and then restart code
