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.

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

The purest execution test in the catalogue and one of the cheapest failures — nothing is lost when a run ends, which is exactly why people attempt the same map four hundred times.

One hit kills, restarts land in under a second, and momentum is mandatory — stopping to think is usually the thing that kills you.

Frame-perfect demands wrapped in the kindest failure state in games — you will die two thousand times and each one costs you half a second.

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.

Instant death in both directions and an instant restart. The difficulty is entirely in how quickly you commit to a floor plan you have already memorised.

You can save anywhere for a resource cost, which turns the escape sequences into a planning problem: no soul links means no checkpoints, and the game does not hand them back.

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.

Momentum platforming with hitboxes that reward commitment and punish hesitation. Funky Mode exists because the late levels ask for a great deal.
