Pretty much what Mizal has already pointed out (the sudden "lol" was unintentionally funny) but I also noticed that you sometimes tend to misjudge sentence length, i.e. cutting them too short.
For example: "Plus your short story assignment is due today. Even though you haven't met the min requirements for word length." I would keep this as a single sentence because the two parts are deeply connected by "even though". There are also other instances in which you used "and" right after a period, but I tend to do that too and it doesn't really sound wrong to me. You probably used short sentences to give rhythm & style to your narrative and that's nice, just be careful not to overdose. And I have issues with sentence length too.
There are also some typos but those happen to everybody, and this is just the first draft anyway.
Looking at the plot, this could be a not-bad story (I'm refraining from saying "good" because there are only 3 pages so far), so stop worrying about minimum site standards. Of course reading other storygames, even if not vampire-related, should help you get a better assessment of the general quality. Just keep writing, I'm sure more or less positive that you can finish this story and make it even better than most other first tries at storygames.
