I wrote this letter to a friend

It is called Flower, and it might seem boring, but it is the most stimulating damn thing I have ever know. You move the controller up and down and over your continental shoulder to steer this one petal with the wind, and as you heal more fields/gorges/what the fuck, your tail begins to cluster bigger and longer with all differently colored flower petals (and the flowers make different instrumental sounds as you bloom them).












I know, it's kind've a guy thing. Anyway the point of this post is for you to find the grammar mistake.
