Ask for the shape of the challenge.

Pure execution with zero consequence: you will restart a seven-second track four hundred times and enjoy every one of them.

The purest execution test on this list and also one of the gentlest, because the retry is faster than your regret.

You can finish it by mashing. The difficulty lives entirely in the gap between finishing it and playing it, and the game is happy to let you ignore that gap forever.

Legible in ten seconds and physical after ten minutes. The ceiling is not comprehension, it is whether your arms can still be in two correct places a second from now.

Each boss is a fixed piece of choreography that you learn by dying to its second phase forty consecutive times.

One input, no health, and no checkpoints outside practice — a level is a single unbroken performance, so failing at ninety-eight percent costs exactly as much as failing at two.

Aggressive rather than punishing — dying costs you almost nothing, so the walls are boss-shaped and the rest is spectacle.

Nothing is hidden and nothing is easy: every technique in the game is visible from the first match and takes hundreds of hours in the hands.

Individually the easiest execution in the genre and the most reading: strings are simple, but every one of them is a decision about whether the assist you also picked is available.

The combos are the advertised difficulty and the easy part. The real one is movement — walking, backdashing and sidestepping are the skill, and no mode in the game teaches them.
