** The AprilFoolsDay 2023 "[[BlatantLies Perfectly Normal Tour]]" stages all feature comically excessive amounts of InterfaceScrew courtesy of Nyochio...but fortunately, it's literally impossible to lose any of the three stages due to the fail condition being a number of Great/Good/Bad judgements that well exceeds the number of notes.

* AprilFoolsDay: For 2023, Nyochio, the mascot cat who's commonly associated with Muni, basically takes over the game. All characters (including generic uninteractable [=NPCs=]) are replaced with Nyochios, some of the locales have Nyochio stickers on the walls, there's a xylophone made of rainbow-colored Nyochios in the Shopping District, and there's a limited-time "[[BlatantLies Perfectly Normal Tour]]" where [[InterfaceScrew Nyochios rain down on the screen as you play]] and [[ForegoneVictory it's impossible to actually fail]] (since the clear requirement for each stage is "Get ''(number that is much higher than the actual notecount)'' Great/Good/Bads or less"). Completing this Tour awards Stray Nyochios that can be exchanged for Nyochio-themed items.

The core gameplay features five lines of tap and hold notes, similar to other lane-based rhythm games. Unique to this game is the addition of Fader and Disc notes, meant to better replicate the controls of a DJ station: Fader notes require the player to move the on-screen slider horizontally so that they catch the notes, Fader Flick notes require the player to flick the fader in the corresponding direction, Scratch notes fall on either of two dedicated lanes (for a total of seven lanes) require the player to flick across the left or right turntable depending on the note while moving the notes back a few pixels, while Scratch hold notes behave like standard hold notes but freeze the notes until the end of the hold.

** This game lacks a "perfect lock" skill that widens the Perfect timing window, but counts Goods towards combo as a counterbalance.

* HopelessBossFight: During RAVE events, [[spoiler:you may encounter a "Dominator" NPC opponent with [[ReadingsAreOffTheScale "Unmeasurable"]] stats. Challenging this event will guarantee a loss. What keeps this from being SchmuckBait is that you will gain a substantial boost to your Matching Bonus, and you will actually get more rewards than challenging a regular opponent, so [[ViolationOfCommonSense you actually want to challenge this type of opponent]].]]

All of that said, this game's charts are explicitly designed around handheld play with thumbs, and players ''have'' achieved Perfect Full Combos on even the hardest songs in the game with thumbs only. The only time a pattern may force 3 or more fingers is when playing on Normal mode (as opposed to Manual), but that's more of a quirk of an assist modifier (which converts some types of non-tap notes into taps) rather than a deliberate design choice.

* ViolationOfCommonSense: Challenging Abyssmare "Dominator" opponents in RAVE, who have "Unmeasurable" stats, will always result in a loss...and a large

* SomeDexterityRequired: ''Groovy Mix'' has a considerably higher skill floor than most other mobile rhythm games (whose gameplay usually just consists of "hit tap notes and hold notes as they scroll down the lanes"). Fader notes don't always have to be held down, only to guide the fader to the notes, and many songs will hammer this lesson in by introducing straight trails with patterns of tap or hold notes that mandate using two hands for them; it's common for a new player to [[DamnYouMuscleMemory try to hold down the trail while hitting the other notes]], resulting in missing either the regular notes, the fader notes, or ''both''. Another aspect that catches newbies off guard are the turntable notes. Scratch notes actually jostle the chart back a little, while hold turntable notes ''freeze'' the main lanes in place until the note passes. Even if you have lots of experience in other rhythm games, you will need to try the easier songs and with lower scroll speed multipliers first to get a hang of the game's signature gimmicks. Perhaps to mitigate this, the game has features to [[GameplayAutomation automate notes by note type]], although using them carries scoring penalties, with auto-played notes not counting towards combo.

* ExplodingCloset: In the event story "Trick or Sexy!?", while Maho is over at Marika's house, Maho opens Marika's closet after the latter asks her to find a particular object she needs help recovering, and ends up being buried in Marika's belongings. A previous event story established Marika as being [[TrashOfTheTitans absolutely terrible at keeping her room clean]], so she just "cleans" her room by stuffing items she doesn't need at the moment into her closet.

** [[InfinityMinusOneSword 3-star cards]] may not have the fancy animations of 4-star cards, and they only max out at level 60 rather than 80, but it is much easier to Limit Break them as you only need one Crystal each time, and because the drop rates for 3-star cards are substantially higher than that of 4-star cards, you can further power them up through Extra Training, which can make them exceed 4-star cards that don't have any Extra Training (good luck trying to get a second copy of the same 4-star card). 3-star cards also appear routinely as event exchange items or rewards, meaning that diligent grinding can get one a 3-star card with Extra Training lv4 without having to pray to the RandomNumberGod. Finally, RAVE events typically have 3-star cards as a trending category, meanind that 3-star cards can really pull your weight when grinding for audience score.
** [[GameplayAutomation Auto-play]] is immensely useful if you don't have the mental energy to actually play charts at the moment, as you can still earn rewards not based on combo. While your reward output will be slightly smaller since you're missing out on the combo bonuses for score, it can still allow you to grind without needing your focus entirely on the game. Auto-play is a godsend in events in particular, as it makes the process of farming event points far less physically taxing; while you will take a small penalty to your event point gain, it's a small price to pay for being able to stay competitive even if you're busy with other activities. However, an update in 2023 now awards ''significant'' bonuses for combos in Manual mode (as in, you can almost double your event points if you play manual and nail a Full Combo), which implicitly penalizes players who are trying to tier with autoplay.

** Abyssmare songs exclusively feature diagonal hold notes (meaning that you press down and then have to follow the note as it crosses over to other lanes).

** The Live Pass unlocks all songs that are not Story unlocks, unlocks a Practice mode that lets the player freely practice sections of songs, adds the Just Perfect note judgement rank, shows whether you hit a note too early or too late as well as a breakdown of that at the end of the song, and enables Technical Score, an alternate scoring system based strictly around note accuracy (i.e. combos and card stats have no effect on it).

* ScoringPoints: In addition to the tradition of gacha-based mobile rhythm games having a scoring system that is partly influenced by what cards you have equipped, the Live Pass also introduced Technical Score, a scoring system based exclusively on note accuracy. The maximum Technical Score appears to be out of 1,000,000 points, but hitting notes with Just Perfect accuracy allows you to get up to 1,005,000 points.
