The idea is interesting because there are not a lot of games like this.

But a brief introduction of how to play will be great, because commonly the "about" is used to know who made the game.

Now, other fact away from that, is that the dot you use to breath, move with a lot of relay, making it annoying to play, and away from that, the "obstacles" represented by words, became repetitive after some minutes of playing.

Away from that, the audio is the best of this game.
