I know you're typing on a DS (don't expect us to remember every detail of your life, so most of us will forget that from time to time), so I'll try to ignore most grammatical mistakes. However, if you have to type on a DS, I would simply recommend not writing a story game at all, and simply wait untill you can make an arrangement so that you can get to a computer. I would suggest your local library if you don't have a computer of your own or it's broken.
Alrighty then, onto the critiqueing:
1.) Where did the pink stone come from? Is the monster's lair a collection of metals and minerals that look appealing to him? Does your protaganist have the power to form projectiles? Does he have an enslaved genie? Is he/she the spawn of the god/goddess of the Earth and therefor can form certain minerals as he/she needs them? I know it seems minor, but minor details and lack thereof can break a story.
2.) I notice you constantly switch tense use. Example "My hands reach for the gashes on my face" completely clashes with "I stumbled onto the road" and other past tense usage. Tense switching can massively infuriate readers.
3.) The pronoun "it" cannot be possesive, so the word "it's" will always mean "it is", nothing more. When you write "rested it's arms" you really mean "rested it is arms". Most people will read it that way, and have to go back and re-read the sentence so it can make more sense. I'm simply telling you this to inform you, because it will both make it easier to type "its" rather than using your stylus to hit an apostraphe every time and because it will make your story more enjoyable.
4.) Why is the monster in the middle of a city? I'm assuming it is because you went from fighting what may or may not be a ferocious monster (lack of details) to crashing into a phone booth. If it is in a place populated enough to have a phone booth, why are there no scared civilians? Like I said, these are minor details, but a small bit of effort goes a long way.
5.) What does "I can't drop my home" mean? I doubt you could pick up your home, let alone drop it. Of course, unless you're homeless and live in a box. I would suggest rephrasing that sentence or adding some backstory in case the quote is significant. I mean, what if a mentor had told him previously "You must always drop what is not neccesary, but to drop what is essential to you would be to drop your very soul" (sorry, that's a horrible quote but I'm writing off the top of my head and I didn't really give it any thought)? Then it would make sense that the protaganist would "holler" that statement, seeing as he knows that to let his home be destroyed by evil would mean giving up his morals and his very identity.
6.) Make your paragraphs longer. One or two sentences are not paragraphs, simply related sentences, and so they require no spacing.
Remember, this is all to help you, so please don't snap at me haha. Don't post a writing sample on a writing site under the writing workshop. This is a place to get criticism, and it will help you when you get more and more tips to help improve your writing.
