Tropes that appear in Miracle Girls Festival:
- And Your Reward Is Clothes
- Anime Theme Song
- Art Shift: Every character is drawn in the same art style that they appear in their respective series.
- Button Mashing: Extreme mode love spamming notes that overlap other notes, which unless you have the reflexes of a ninja, you'll miss several notes.
- Color-Coded for Your Convenience: The colors of the notes correspond with the PS Vita's face buttons.
- The rankings of how accurately you press the buttons also have their own colors: Sad is blue, Safe is green, Fine is silver and Cool is gold.
- There are two different colors of worst, purple is pressing the right button at the wrong time, orange is the wrong note.
- The rankings of how accurately you press the buttons also have their own colors: Sad is blue, Safe is green, Fine is silver and Cool is gold.
- Cross Through: The featured intellectual properties don't interact with each other.
- "Do It Yourself" Theme Tune: Every song in the game is sung by the characters dancing to it.
- Earn Your Fun: Unlocking extra difficulties and the full versions of songs requires you to complete multiple achievements on a bingo card. These can be something that will happen during normal such as getting 10000 Miracle Coins from the same song to something more taxing such as getting no Sad's or Worst's on the Normal version of the song.
- Fake Difficulty: The Extreme versions use overlapping notes, a lot, Extreme!Mashiro World and Extreme!Koi wa Chaos no Shimobenari are particularly egregious about this.
- Ironically, the Easy and Normal versions of Your Voice are harder that the hard version as many of the notes don't match the rhythm of the music.
- Fanservice: Both gold base statues come with 2 voice clips each, one is an introduction, the other 3 are quotes of the character from their series.
- If you get Miracle Fever Chance, some references to the songs work will appear on-stage. Some of them are subtle such as Alice's letter to Shinobu from the start of the series showing up on the big screen at the end of Your Voice; some are very obvious such as the giant Shantak-kun balloons during Taiyo Iwaku Moeyo Chaos.
- On the sexual side, Vivid Shining Sky opens with an ass-shot of Akane.
- Gameplay Grading: The timing for the notes have five grades: Worst, Sad, Safe, Fine, and Cool.
- The results at the end of the song are O.K, Standard, Great, Excellent and Miracle.
- Gotta Catch 'Em All: By spending Miracle Coins and Miracle Lots, you can randomly win silver or gold base (respectively) statues of all 48 characters for both of their costumes resulting in 192 statues to collect.
- Harder Than Hard: Extreme difficulty which has the hardest and cheapest levels in the game.
- Improbably Female Cast: The game isn't called Miracle Girls Festival for nothing.
- Interface Spoiler: Didn't finish the story mode before investing in any statues or alternate costumes or even looking at the cover of the game? Congrats, you've just been spoiled to the Project 575 girls being playable.
-
Licensed Game: All the characters featured come from various Light Novels, Manga, and Anime unrelated to Sega. - Life Meter: Ura-Play mode plays like this because if you get too many Worst's, Sad's, or Safe's, the song ends.
- Logo Joke: The Sega logo has a seiyuu of one of the characters singing "See-gaaaaa!" similar to how old Sega games had the "See-gaaaaa!" yell.
- Money for Nothing: Once you've bought all the songs, alternate costumes, statue backgrounds and gotten all the statues, you won't have anything left to spend your Miracle Coins or Miracle Lots on.
-
Nintendo Hard: Extreme Mode for some songs is this. - Rhythm Game
- The Cameo: Getting Miracle Fever Chance will reference something from that song's universe such as the Sonota sisters in the audience becoming back up dancers or the eggplant hot-air balloon.
- Unexpected Gameplay Change: Expand-Play and Ura-Play difficulties. The former has the notes starting off tiny and the player has to time their button presses when the note is at normal size. The latter has the notes moving faster and the Miracle Fever gague starts off full, getting Worst's, Sad's, and Safe's causes the gague to deplete and you lose if the gauge empties.
