Ask for the shape of the challenge.

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.

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

Tool-based puzzles that stay scrupulously fair, while the optional stars quietly assume you will break the rules the tutorial spent an hour teaching.

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.

The rules are the puzzle, so being stuck feels less like failing and more like simply not having had the thought yet.

It is not hard to survive so much as hard to be told nothing and still choose the right direction.

Badges let you paper over whichever skill you lack. The special world at the end is the only place it stops being polite about that.

There is no fail state, only the quiet friction of guessing where somebody else would keep their mugs.

Two players, one screen, no difficulty setting. The hard part is coordination, and the game restarts you both a second after it goes wrong.
