The settings cannot be set per each player, so this would not work.  To solve this, there are 3 servers up to play on, and all of them are linked together as far as scores go.

I can't see people liking that idea.  Everyone is free to set up a new camera however they wish, which you can change with a command in-game.  Forcing people to use a certain camera, especially in a gametype like sumo, I can't see going over well.

4. should the box (boxes, if you take my 1st and 3rd suggestions) not be a little bigger? 
I'm not sure why you would speed it up and make a bigger map.  That seems to make it kind of pointless to me.  But, I wanted the map to be small for a reason.  You can still last for quite a while in there, but it's resembling the survival servers.  So, the more you collect, the longer your tail grows, and the harder it is to survive.  I don't think speeding people up would be necessary.  I like it having a sumo feeling, and that would change it too much IMO.

I was thinking about this.  People seem to be scared to touch them, even though there's a message saying that's what you do.  The point of it was that the snake is supposed to be eating apples, but people see red and avoid it.  I think it's something people will get used to though.  It's not too hard to figure out when nothing is happening except that zone sitting there.  Eventually, I think they'll touch it out of curiosity if they refuse to read the console message.

Outside of flaming,  pretty much all feedback is good feedback.  It gives me an idea of what people think about it and what I could do to make it better for the majority of players.
