Hahah, I love the big rooms, too! v1.2 is introducing regularly-scheduled tournaments, which start at 32 players and then eliminate a few people after each round until it's down to the last man standing. I'm also working on another item that any player can use to make a temporary giant room. :D
Okay...so when I begin, I get things like combos of two. I look at the leader boards, and some people got something like 1 billion or 997 million, and I just think that's impossible. Then I buy a few launchers. (Just so you know, they're still going now)
