Advice
I had an idea for multiplayer that i thought would be really cool. (but also probably impossibly difficult)
An advice option.
The way this would work, is that the spectators (and the people in queue) would see a button under the fighters' names that says "give advice." When you click it, you would be able to control the tori you're giving advice to. Then, when you've press space, the corresponding fighter will get a notification saying "[insert name] wants to give you advice!" and there'll be a button that says "accept" and a button that says "decline." if you press accept, your toris joints will change to whatever the advice giver did to them. and if you don't like it you can just change it back blah blah blah. also if you accept the advice and press space, it'll say that you took it the in the chat.
down sides:
bad advice.
beginners just taking advice from a pro every time.
flooding of advice.
and, of course, this could be enabled and disabled. it'd be really helpful for sparring and such.
