Ask for the shape of the challenge.

Map and compass navigation with no waypoint marker is the only thing in it that asks anything of you at all.

There is nothing here to fail. It is in the catalogue because the bottom of the scale has to mean something for the top of it to.

Gentle to look at and quietly ruthless to score — the tile you place carelessly on turn ten is the one that ends the run four hundred turns later.

Gentler than the first game and better taught. The co-op campaign is where the difficulty actually lives, because it needs two people to see the same solution at once.

Death is frequent, instant and immediately retried, and every puzzle is solvable from what the room shows you. Nothing here is hidden from a patient player.

Hard for exactly as long as it takes the idea to arrive, then trivial — a game of realisations rather than of skill.

No reflexes and no fights — you fail by having rolled badly on the question of who you decided to be twenty hours ago.

A lullaby until the drop speed crosses whatever your reading threshold happens to be, at which point it becomes a pure reflex test with a very good soundtrack.

The only thing gating progress is knowledge inside your own head, which makes it unspoilable once and unplayable if you look it up.

A blockbuster that expects to be finished, with the actual demands parked in optional bosses you can walk past without the story noticing.
