YMMV / WACCA

• Memetic Mutation: Missless!^Explanation Many players have noted that a Missless is, in fact, awarded for missing 1-5 times, not missing zero notes like the phrase implies. The phrase is also invoked by players out of frustration on 1-miss runs in other rhythm games. Note that its memetic status isn't limited to English-speaking players; it's a point of confusioni for Japanese players as well.
• Nightmare Fuel: The sound effects for a fatal cabinet error are terrifying, consisted of a series of descending detuned saw-waves that won't sound very far-fetched for a horror game.
• Scrappy Mechanic: The game will not let you use your Aime card to play if you already have data for the game in another region. (For example, if you have ever played the game in Japan with your card, you cannot use it in the United States.) This stands out in comparison to other net-enabled arcade games, which will either let you use data started from another region (most rhythm games) or make you use new region-specific data but at least not make you purchase a new card (maimai DX).
