YMMV / Nostalgia (BEMANI)

• Accidental Innuendo: One of the track titles is "PLEASURE STREAM".
• Sequel Difficulty Drop: The game is considerably easier than its Spiritual Predecessor Keyboardmania, in part due to not having a lifebar system and notes corresponding to ranges of keys rather than specific keys, allowing for a degree of leniency. Players can also turn on modifiers to automate left- or right-hand notes, if they are still having trouble.
• Spiritual Adaptation: It's practically an arcade version of Deemo. Both games are based around the piano and involve hitting notes of varying width, and the soundtracks are similar in style as well.
