M256'S PROFILE

I need a bit of help in my game description.

Here's the original:
Some time ago, a girl, whose name is unknown, had a broken life. Living alone on her apartment, she decided to get a stereo system in order to feel better about herself. After buying a particular old and large stereo system, she discovered what lied beyond the electronic device: it was a portal.

But where did the portal lead? The answer was a dream-like world that reflected her, populated by several beings who were living there somehow. However, she recieved a simple mission, its reason not disclosed: she had to get 30 mysterious objects, called orbs, scattered across the world like papers on the wind. Aiding her are some items that change her appearance, called by convenience "Effects", also found across the bizarre landscapes.

But what to make about the orbs and their purposes? Some say that they were memories of her rotten life, as she attempts to fix herself and uncover the truth. And thus, she nicknamed herself "Me" and started the fetch quest on that land.

What do you suggest for improving the description? Did I make any english mistakes (it's not my native language, so...)
