It's a bit funny that a game about "relaxing" can be so stressful - but it was very fun! The music and art are very polished and lend a great feel.
The only criticism I have (and it's so small) is that the leaf and bacteria objects can look quite similar due to their color - and I would sometimes try to blow away the leaves because I thought "my meditation would be ruined if I sucked in a leaf". Maybe a more distinct or readable shape could be used for that sprite, like a light blue puff-of-air or something?
