Sister site Gamasutra have confirmed with The Behemoth that Castle Crashers is selling incredibly well - and that its well over 250,000 players now.

“I’m pleasantly surprised that so many people are playing the game,” says Behemoth lead artist Dan Paladin to Gamasutra, confirming that a quarter of a million players are now on the game's leaderboards. “I was optimistic and hopeful for Castle Crashers but I wasn't prepared for the reception it got."

They've also confirmed that they've been working very hard on a patch for the game - as many people (including myself) have had a lot of difficulty getting online, with people dropping out or the game freezing before hand. I love the game - but I'm waiting for a patch before I get back into it.
