1-X: A Dance of Fire and Ice: "But you need to remember it"

("it" = "m → n. It means that the level will only be displayed from the mth to nth block in front of you")

(For example, "-3,3" means you can only see three tiles behind and three tiles in front. If the two numbers are the same, for example "4,4", that means the fourth tile in front will be displayed)

~~~~~~~~~~~~~~

2-X: Offbeats: "But the speed is getting faster"

("*n. It means getting n times faster". Lots of pseudo gameplay)

Remaster: {?}

(No title, but the curse seems to be that the song plays over itself with a delay of 16 beats, using midspins to hit both rhythms)

~~~~~~~~~~~~~~

3-X: THE WIND-UP: "But it's like other game"

(Different style of rhythm game altogether, with falling tiles)

~~~~~~~~~~~~~~

4-X: Love Letters: "But you need to do math problems"

(Examples like "repeat 2^2 times", and "if the answer is correct, hit it")

~~~~~~~~~~~~~~

5-X: The Midnight Train: "But if the orbit is greater than 180 degrees, it will become twice the speed"

(Opposite of "MO-X")

~~~~~~~~~~~~~~

6-X: PULSE: "But your position will randomly change"

("→m is moving forward by m cells m← is moving backward by m cells")

(Jumps forward/backward randomly)

~~~~~~~~~~~~~~

7-X: Spin 2 Win: "But symbols will make your speed faster"

~~~~~~~~~~~~~~

8-X: Jungle City: "But mathematical algorithms can change the properties of tiles"

("But with added long presses for planetary ascent". Don't know why the title is worded like this, but hold tiles are added whenever the planets move upwards)

~~~~~~~~~~~~~~

9-X: Classic Pursuit: "But it's the opposite of 8-X"

(Holds are added for planetary descent)

~~~~~~~~~~~~~~

10-X: Butterfly Planet: "But repeating the orbit three times change the number of balls"

(Every three {something}, the planet number toggles. I'm just not sure what.)

~~~~~~~~~~~~~~

11-X: Heracles: "But it's complete"

(Extended version)

~~~~~~~~~~~~~~

12-X: Artificial Chariot: "But the closed shape is growing exponentially"

(Similar to 12-X?, but instead of adding one, the pattern is as follows: the first time is 1^1, the second time is 2^2, the third time is 3^3, the fourth time is 4^4, and so on. However, the chain resets once a different shape shows up, so there aren't thousands of triangles. (5^5 is 3,125.))

• (This might not be the case, though, as in "You Haven't Forgotten Any Night", when this Furry shows up, the pattern is "1, 4, 9, 16,  26, 42". This leads me to believe that the pattern is actually following an exponential function, but which one isn't clear to me. (I also might have miscounted, so take this with a grain of salt.))

XC-X: Credits: "But repeating the blocks becomes a Mid-Spin"

(If multiple of the same tile angle are next to each other, then the latter ones are replaced with midspins)

~~~~~~~~~~~~~~

XF-X: Third Wave Flip Flop: "But except for the horizontal blocks, they all become rotated in the middle"

(All tiles except horizontal ones become midspins)

~~~~~~~~~~~~~~

XH-X: Final Hope: "But it turned into the Final Despair"

(Much harder/impossible charting)

~~~~~~~~~~~~~~

XM-X: Miko Skip: "But angles greater than 180 degrees are split into two equal angles"

(The easiest to understand example is that 360˚ tiles are split into two 180˚ tiles. This is also the extended version)

~~~~~~~~~~~~~~

XN-X: Trans-Neptunian Object: "But symbols change the number and status of planets"

(Don't know what "status" means; maybe they also changed the speed. Also, extended version jumpscare)

~~~~~~~~~~~~~~

XR-X: Rose Garden: "But the symbol changes the long press state of the block"

(Gameplay events toggle on and off hold notes, and the holds only occur every other tile. They also used the extended version for this)

~~~~~~~~~~~~~~

XS-X: Party of Spirits: "[But] half the angle of all closed shapes by multplying the number of edges by two"

(For example, a square (usually made up of 90˚ tiles) is turned into an octagon (which has an exterior angle of 45˚). A bit complicated to understand, and certain shapes don't seem to count, but the song isn't altered)

~~~~~~~~~~~~~~

ML-X: La nuit de vif: "But sometimes you need to click quickly"

(Quick time events like 12-EX)

~~~~~~~~~~~~~~

MN-X: Night Wanderer (cnsouka Remix): "But if the orbit repeats, it accelerates on the repeated orbit"

(If a pattern repeats, the song gets faster, but if the pattern is interrupted, the tempo resets)

~~~~~~~~~~~~~~

MO-X: EMOMOMO: "But you had hallucinations"

(Cool tile effects, flashing lights, and skipping/returning to parts of the song like Nightmares of the same song)

~~~~~~~~~~~~~~

PA-X: Distance: "But in places where Mid-Spin exists, there are multiple Mid-Spin"

(The added midspins aren't spammed, but added according to the cardinal and intermediate directions. Also, they used the extended version)

~~~~~~~~~~~~~~

RJ-X: Fear Grows: "But after copying this brick, it can form a regular polygon, so multiple clicks are required"

("But double rhym when the angle is (180-360/n (n∈Z))")

({Certain tiles} are pseudo-multitaps)
