As first here is my suggestion for this cool game (really, I love it!):
Teamplaying with an option to allow teams and creating them with other players, the teammates would have nearly the same colours (for example lightblue blue and dark blur would be teammates). And the teams would need:
-Option to change the time per round (for host)
-Team chat (whisper like)
A map editor to crate maps where you can play on would be great!
And probably a Moderator system. Some ppl would get mods and they could help the game by kicking/banning/muting rulebreaking or annoying users and would also be helpful by finding bugs and probably by testing brand new things the playes will be later able to buy/unlock or another new things!
I would really like to see these things ingame!
And now the bug: It mosly appears randomly and doesn't let (most times the host) do anything like choosing start and skipping his round...
Thanks for reading!
