You carry a world on your back. You can enter it. Inside it there is another world you can also carry, and you can carry the world you are standing in into the world you are carrying. If that sentence made sense on the first read, this game will still surprise you.

One idea, developed properly

Cocoon is made by the lead designer of Limbo and Inside, and the pedigree shows in a specific way: it introduces its mechanic in the first five minutes and spends the remaining seven hours finding implications rather than adding systems. There is no upgrade. There is no second mechanic. Every puzzle is the same mechanic understood better.

The result is a difficulty curve with no jumps. I never looked anything up and I never got stuck for more than four minutes, and both of those are the result of extraordinary care in ordering the rooms.

No words at all

There is no dialogue, no text, no map and no tutorial prompt. Everything is taught through geometry and colour, and it works so completely that you will not notice the absence until it is over. The three boss fights are the only friction and they exist mostly to punctuate.

Where it slips

It is seven hours and it is priced like a small game, which is fair, but the ending arrives just as the nesting is becoming genuinely complex. There is a version of this that ran ten hours and had two more layers of implication, and I would have played it.

The bosses also break the pacing rather than raising it — they are the one place where the game asks for reflexes it has not trained.

The verdict

Nearly flawless at what it attempts, and what it attempts is modest. Seven hours, no filler, no frustration, and a central idea that nothing else has.

An ideal handheld game. Play it in two sittings.

Accessibility

  • No text and no dialogue anywhere, which removes the language barrier entirely
  • Full remapping; one action button and a stick is the whole control scheme
  • No timed sequences and no fail states outside three short boss fights
  • Colour is used to distinguish worlds, with distinct shapes as a secondary cue
