Err... I thought Carnival Phantasm has been over since I heard about the DVD release coming out soon. But, apparently - there a extra special episode that came out and it's somewhat sadly disappointing. You basically get to watch a "gameplay" of the cast. Though, it's taunting that the game doesn't "exist" and you don't get to "play" it. Overall, it's a short and is not much of a downer.
Conclusion: Taunting teaser gameplay.
