I don't know if there are levels already making use of the Pool/Snooker concept. But it would be a lot of fun for a puzzle to play a game of Pool or Snooker with the big ball
What about a football version (in Mulitiplayer obviously) where you can get killed by the Ball?
we might do something like pool or bowling in a dlc at some point. It would be fun to make a giant pool table
multiplayer is out of the question though, that would require a total rewrite of large parts of the game.
i was gonna suggest a feature that lets us see other people's ball skins, and we'd get to play with their balls.
