It's a good game, and the story line is decent, but the dialogue SERIOUSLY needs a proof-reader who speaks fluent english to go over it. It's not illegible, but it's kind of painful to read sometimes.
It's not so bad at the beginning, but it's quite noticeable the further along the story progresses. Your verb conjugations are often wrong, when you should be using the past continuous tense(was having) you tend to phrase it as a past perfect tense(had), things like that. Easy mistakes to make, but they affect the flow when reading. English is a very messy language, I would hate to learn it as a second language.
